* Revert r703998.
  The call to apr_socket_timeout_set before apr_socket_connect already sets the
  socket to non-blocking mode because the timeout of the socket is -1 after creation. A further
  call to apr_socket_timeout_set (after the connect call does not do this, because the old
  and the new timeout are >=0). The further code expects the socket to be in non-blocking
  mode, otherwise we have regressions with ssl. This can be notified by running t/ssl/proxy
  on 2.2.x which runs much much slower with the patch applied. This does not happen
  on trunk because the socket is set back to non blocking by the core output filter
  (async write completion).

 Changes with Apache 2.3.0
 [ When backported to 2.2.x, remove entry from this file ]
 
-  *) mod_proxy: Make the connection timeout to backends work by temporarily
-     setting the socket to non blocking mode.
-     [Matt Stevenson <mavricknzwork yahoo.com>]
-
   *) Worker MPM: Crosscheck that idle workers are still available before using
      them and thus preventing an overflow of the worker queue which causes
      a SegFault. PR 45605 [Denis Ustimenko <denusk gmail.com>]
