Description:
------------
Sometimes, on Windows7 with PHP5.3+, stream_socket_recvfrom() returns false (the documentation says
that it always returns a string but the source code says the opposite, it can return false), and I
have no idea why. It happens only on Windows7 a priori. Basically, I have a client and a server as
bellow.

Test script:
---------------
Client.php

<?php
 
$client = stream_socket_client(
    'tcp://127.0.0.1:9001',
    $errno,
    $errstr,
    30,
    STREAM_CLIENT_CONNECT
);
echo 'Received ';
var_dump(stream_socket_recvfrom($client, 6));


Server.php

<?php
 
$server = stream_socket_server(
    'tcp://127.0.0.1:9001',
    $errno,
    $errstr,
    STREAM_SERVER_BIND | STREAM_SERVER_LISTEN
);
echo 'Up & listen…', "\n";
$client = stream_socket_accept($server);
echo 'New connection', "\n";
stream_socket_sendto($client, 'foobar');
echo 'Sent “foobar”', "\n";

Expected result:
----------------
Client.php
Received: string(6) "foobar"

Server.php
Up & listen…
New connection
Sent “foobar”

Actual result:
--------------
Client.php
Sometimes: Received: string(6) "foobar"
Sometimes: Received: bool(false)

Server.php
Up & listen…
New connection
Sent “foobar”
