// = DESCRIPTION
//     This is a test of the <ACE_Acceptor> and <ACE_Connector>
//     classes. The test forks processes or spawns threads (depending
//     upon the platform) and then executes client and server allowing
//     them to connect and exchange data.  The test also illustrates
//     how the <ACE_Strategy_Connector> works by showing how you can
//     cache connections on the client.
