Description:
------------
If a connection has already been established, pfsockopen will hang for 30 seconds before returning the correct persistent socket. strace reports the following:

...
connect(3, {sa_family=AF_INET, sin_port=htons(11211), sin_addr=inet_addr("10.0.0.16")}, 16) = -1 EINPROGRESS (Operation now in progress)
select(4, [3], [3], [3], {60, 0})       = 1 (out [3], left {60, 0})
getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
fcntl64(3, F_SETFL, O_RDWR)             = 0
select(4, [3], NULL, NULL, {60, 0}
*hang*

The following patch seems to fix it:

Maybe this needs backporting?

Reproduce code:
---------------
<?
$fp = pfsockopen("rembrandt", 11211);
$fp = pfsockopen("rembrandt", 11211);
?>
