Description:
------------
From docs:

"Returns TRUE if the file pointer is at EOF or an error occurs
(including socket timeout); otherwise returns FALSE."

...

"If a connection opened by fsockopen() wasn't closed by the server,
feof() will wait until a timeout has been reached to return TRUE. The
default timeout value is 60 seconds. You may use stream_set_timeout() to
change this value."



feof() dows not wait and returns TRUE instead of FALSE if timeout
reached (server does not closed connection and there is no data in
timeout time slot).

* server does not closed connection,
* timeout wa reached

Reproduce code:
---------------
$s = stream_socket_client('tcp://www.php.net:80', $errno, $errstr, 10,
STREAM_CLIENT_CONNECT);

stream_set_timeout($s, 4);

$response = '';
while (feof($s) !== TRUE) {

   if (($foo = @fread($s, 1024 * 8)) === FALSE) return NULL;
   $response = $response . $foo;
};

print "OK";

Expected result:
----------------
prints "OK" approx. in 4 seconds

Actual result:
--------------
hangs forever
