    10 ** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.

    11 **

    12 ** Modification History:

    13 **

    14 ** 19-May-97 AGarcia - separate the four join tests into different unit test modules.

    15 **		    AGarcia- Converted the test to accomodate the debug_mode flag.

    16 **          The debug mode will print all of the printfs associated with this test.

    17 **		    The regress mode will be the default mode. Since the regress tool limits

    18 **          the output to a one line status:PASS or FAIL,all of the printf statements

    19 **		    have been handled with an if (debug_mode) statement.
