+#
+# Class that encapsulates process creation, monitoring and cleanup
+#
+# Spawns a monitor process which spawns a new process locally or
+# remote using subclasses My::Process::Local or My::Process::Remote etc.
+#
+# The monitor process runs a simple event loop more or less just
+# waiting for a reason to zap the process it monitors. Thus the user
+# of this class does not need to care about process cleanup, it's
+# handled automatically.
+#
+# The monitor process wait for:
+#  - the parent process to close the pipe, in that case it
+#    will zap the "monitored process" and exit
+#  - the "monitored process" to exit, in which case it will exit
+#    itself with same exit code as the "monitored process"
+#  - the parent process to send the "shutdown" signal in which case
+#    monitor will kill the "monitored process" hard and exit
+#
+#
+# When used it will look something like this:
+# $> ps
+#  [script.pl]
+#   - [monitor for `mysqld`]
+#     - [mysqld]
+#   - [monitor for `mysqld`]
+#     - [mysqld]

+  Utility program that encapsulates process creation, monitoring

+
+  Usage:
+    safe_process [options to safe_process] -- progname arg1 ... argn
+
+  To safeguard mysqld you would invoke safe_process with a few options
+  for safe_process itself followed by a double dash to indicate start
+  of the command line for the program you really want to start
+
+  $> safe_process --output=output.log -- mysqld --datadir=var/data1 ...
+
+  This would redirect output to output.log and then start mysqld,
+  once it has done that it will continue to monitor the child as well
+  as the parent.
+
+  The safe_process then checks the follwing things:
+  1. Child exits, propagate the childs return code to the parent
+     by exiting with the same return code as the child.
+
+  2. Parent dies, immediately kill the child and exit, thus the
+     parent does not need to properly cleanup any child, it is handled
+     automatically.
+
+  3. Signal's recieced by the process will trigger same action as 2)

+/*
+  Utility program that encapsulates process creation, monitoring
+  and bulletproof process cleanup
+
+  Usage:
+    safe_process [options to safe_process] -- progname arg1 ... argn
+
+  To safeguard mysqld you would invoke safe_process with a few options
+  for safe_process itself followed by a double dash to indicate start
+  of the command line for the program you really want to start
+
+  $> safe_process --output=output.log -- mysqld --datadir=var/data1 ...
+
+  This would redirect output to output.log and then start mysqld,
+  once it has done that it will continue to monitor the child as well
+  as the parent.
+
+  The safe_process then checks the follwing things:
+  1. Child exits, propagate the childs return code to the parent
+     by exiting with the same return code as the child.
+
+  2. Parent dies, immediately kill the child and exit, thus the
+     parent does not need to properly cleanup any child, it is handled
+     automatically.
+
+  3. Signal's recieced by the process will trigger same action as 2)
+
+  4. The named event "safe_process[pid]" can be signaled and will
+     trigger same action as 2)
+
+  WARNING! Be careful when using ProcessExplorer, since it will open
+           a handle to each process(and maybe also the Job), the process
+           spawned by safe_process will not be closed off when safe_process
+           is killed.

+#
+# Coding style directions for this perl script
+#
+#   - To make this Perl script easy to alter even for those that not
+#     code Perl that often, keeep the coding style as close as possible to
+#     the C/C++ MySQL coding standard.
+#
+#   - All lists of arguments to send to commands are Perl lists/arrays,
+#     not strings we append args to. Within reason, most string
+#     concatenation for arguments should be avoided.
+#
+#   - Functions defined in the main program are not to be prefixed,
+#     functions in "library files" are to be prefixed with "mtr_" (for
+#     Mysql-Test-Run). There are some exceptions, code that fits best in
+#     the main program, but are put into separate files to avoid
+#     clutter, may be without prefix.
+#
+#   - All stat/opendir/-f/ is to be kept in collect_test_cases(). It
+#     will create a struct that the rest of the program can use to get
+#     the information. This separates the "find information" from the
+#     "do the work" and makes the program more easy to maintain.
+#
+#   - The rule when it comes to the logic of this program is
+#
+#       command_line_setup() - is to handle the logic between flags
+#       collect_test_cases() - is to do its best to select what tests
+#                              to run, dig out options, if needs restart etc.
+#       run_testcase()       - is to run a single testcase, and follow the
+#                              logic set in both above. No, or rare file
+#                              system operations. If a test seems complex,
+#                              it should probably not be here.
+#
+# A nice way to trace the execution of this script while debugging
+# is to use the Devel::Trace package found at
+# "http://www.plover.com/~mjd/perl/Trace/" and run this script like
+# "perl -d:Trace mysql-test-run.pl"
