+ *
+ * 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.
