/*
** File: instrumt.c
** Description: This test is for the NSPR debug aids defined in
** prcountr.h, prtrace.h, prolock.h
**
** The test case tests the three debug aids in NSPR:
**
** Diagnostic messages can be enabled using "instrumt -v 6"
** This sets the msgLevel to something that PR_LOG() likes.
** Also define in the environment "NSPR_LOG_MODULES=Test:6"
**
** CounterTest() tests the counter facility. This test
** creates 4 threads. Each thread either increments, decrements,
** adds to or subtracts from a counter, depending on an argument
** passed to the thread at thread-create time. Each of these threads
** does COUNT_LIMIT iterations doing its thing. When all 4 threads
** are done, the result of the counter is evaluated. If all was atomic,
** the the value of the counter should be zero.
**
** TraceTest():
** This test mingles with the counter test. Counters trace.
** A thread to extract trace entries on the fly is started.
** A thread to dump trace entries to a file is started.
**
** OrderedLockTest():
**
