Description:
------------
when I use the STREAM_CLIENT_ASYNC_CONNECT flag to my stream_socket_client() call, it just doesn't connect() at all.

Reproduce code:
---------------
<?
echo "trying ...\n";
stream_socket_client("tcp://127.0.0.1:80", $errno, $errstr, 10, STREAM_CLIENT_ASYNC_CONNECT);
sleep(10);
?>

Actual result:
--------------
using strace on the following script gives :

--------------------------------------------
write(1, "trying ...\n", 11trying ...
)            = 11
rt_sigprocmask(SIG_BLOCK, [CHLD], [RTMIN], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [RTMIN], NULL, 8) = 0
nanosleep({10, 0}, {10, 0})             = 0
--------------------------------------------

in other words the connect() syscall is never called at all between the echo and sleep.

on the other hand, when I remove STREAM_CLIENT_ASYNC_CONNECT, connect() is called.
