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.
