+/***********************************************************************
+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-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.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
