// = FILENAME
// Thread_Pool_Reactor_Test.cpp
//
// = DESCRIPTION
// This program is a torture test of thread pool reactors. It
// starts by spawning several server threads waiting to handle
// events. Several other client threads are spawned right after
// to initiate connections to server threads. Each connection
// adds a new Svc_Handler into the TP_Reactor and sends out
// several "requests" to the server thread. After the connection
// is closed, the Svc_Handler is removed from the TP_Reactor.
// Each message is treated as a separate request by the server so
// two consecutive requests might be serviced by two different
// threads.
//
// Usage: Thread_Pool_Reactor_Test [-r <hostname:port#>]
// [-s <server thr#>] [-c <client thr#>] [-d <delay>]
// [-i <client conn attempt#>] [-n <client request# per conn>]
//
// Default value:
// <hostname:port#>: ACE_DEFAULT_RENDEZVOUS
// <server thr#>: ACE_MAX_THREADS
// <client thr#>: ACE_MAX_ITERATIONS
// <client conn attempt#>: ACE_MAX_ITERATIONS
// <client req# per conn>: ACE_MAX_THREADS
// <delay>: 50 usec
