Description:
------------
stream_select() returns 0 while the first array provided does contain a changed socket (one waiting to be stream_socket_accpet()'ted)

same code does work with same php version on gentoo on a P2 text machine.
My solution is to use $count = count($read); afther the stream_select()

Reproduce code:
---------------
$socket = stream_socket_server("tcp://0.0.0.0:4141", $errno, $errstr);
$read[] = $socket;

$mod_fd = stream_select($read, $_w = NULL, $_e = NULL, 5);
echo $mod_fd;
$mod_fd = count($read);
echo $mod_fd;

Expected result:
----------------
twice 1 when there is a waiting socket

Actual result:
--------------
0 and 1
