Update the test suite to provide a mechanism to temporarily pause the unit
tests if a test failure occurs.  This will make it possible to examine the
server more closely in the state that caused the failure.  Before pausing the
tests, the test suite will create a watchdog file, and when that file is
removed, the server will resume running the test cases.
