+ * Under Unix, Apache can be told to shutdown or restart by sending various
+ * signals (HUP, USR, TERM). On NT we don't have easy access to signals, so
+ * we use "events" instead. The parent apache process goes into a loop
+ * where it waits forever for a set of events. Two of those events are
+ * called
+ *
+ * apPID_shutdown
+ * apPID_restart
+ *
+ * (where PID is the PID of the apache parent process). When one of these
+ * is signalled, the Apache parent performs the appropriate action. The events
+ * can become signalled through internal Apache methods (e.g. if the child
+ * finds a fatal error and needs to kill its parent), via the service
+ * control manager (the control thread will signal the shutdown event when
+ * requested to stop the Apache service), from the -k Apache command line,
+ * or from any external program which finds the Apache PID from the
+ * httpd.pid file.
+ *
+ * The signal_parent() function, below, is used to signal one of these events.
+ * It can be called by any child or parent process, since it does not
+ * rely on global variables.
+ *
+ * On entry, type gives the event to signal. 0 means shutdown, 1 means
+ * graceful restart.

+ * master_main()
+ * master_main() runs in the parent process. It creates the child
+ * process which handles HTTP requests then waits on one of three
+ * events:
+ *
+ * restart_event
+ * -------------
+ * The restart event causes master_main to start a new child process and
+ * tells the old child process to exit (by setting the child_exit_event).
+ * The restart event is set as a result of one of the following:
+ * 1. An apache -k restart command on the command line
+ * 2. A command received from Windows service manager which gets
+ * translated into an ap_signal_parent(SIGNAL_PARENT_RESTART)
+ * call by code in service.c.
+ * 3. The child process calling ap_signal_parent(SIGNAL_PARENT_RESTART)
+ * as a result of hitting MaxConnectionsPerChild.
+ *
+ * shutdown_event
+ * --------------
+ * The shutdown event causes master_main to tell the child process to
+ * exit and that the server is shutting down. The shutdown event is
+ * set as a result of one of the following:
+ * 1. An apache -k shutdown command on the command line
+ * 2. A command received from Windows service manager which gets
+ * translated into an ap_signal_parent(SIGNAL_PARENT_SHUTDOWN)
+ * call by code in service.c.
+ *
+ * child process handle
+ * --------------------
+ * The child process handle will be signaled if the child process
+ * exits for any reason. In a normal running server, the signaling
+ * of this event means that the child process has exited prematurely
+ * due to a seg fault or other irrecoverable error. For server
+ * robustness, master_main will restart the child process under this
+ * condition.
+ *
+ * master_main uses the child_exit_event to signal the child process
+ * to exit.
