+/***********************************************************************
+**  1996 - Netscape Communications Corporation
+**
+** Name: cvar2.c
+**
+** Description: Simple test creates several local and global threads;
+**              half use a single,shared condvar, and the
+**              other half have their own condvar. The main thread then loops
+**              notifying them to wakeup.
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**           The debug mode will print all of the printfs associated with this test.
+**           The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**           have been handled with an if (debug_mode) statement.

+notified.  They will all wakeup on a 1 second timeout.                  \n\

+third thread is notified, the other threads are expected to timeout     \n\
+correctly.                                                              \n\
