/*
 *
 * Notes:
 * [1] lth. The call to Sleep() is a hack to get the test case to run
 * on Windows 95. Without it, the test case fails with an error
 * WSAECONNRESET following a recv() call. The error is caused by the
 * server side thread termination without a shutdown() or closesocket()
 * call. Windows docmunentation suggests that this is predicted
 * behavior; that other platforms get away with it is ... serindipity.
 * The test case should shutdown() or closesocket() before
 * thread termination. I didn't have time to figure out where or how
 * to do it. The Sleep() call inserts enough delay to allow the
 * client side to recv() all his data before the server side thread
 * terminates. Whew! ...
 *
 ** 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.
