+** 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():
