Subject: Modified client to send a PUSH_REQUEST message to server 1 second
 after connection initiation rather than 0 seconds after. Successive
 PUSH_REQUEST messages after the first will continue to be sent at 5 second
 intervals until a response is received.  This tends to speed up the client
 connection sequence by 4 seconds because the first PUSH_REQUEST message is
 usually sent too soon and is dropped, causing a wait of 5 seconds until the
 next PUSH_REQUEST message is sent.

Version 2.1_rc19d
