From: Daniel Henrique Barboza <danielhb@linux.vnet.ibm.com>

There was a condition in the close of the Websocket that wasn't
being covered properly by the pushserver prior to this patch. The
fix was to put an additional condition to close our remote socket
reference when we receive no data from it, instead of relying just
in the Except call to do it.

While we're at it, a cleanup was made in the code to remove a
condition of a 'CLOSE' message that was being sent in the first
versions of the Pushserver but didn't make upstream.
