Description:
------------
hello i was using archlinux 32 bits version on pentium3 
i bought an intel core 2 duo e6600 and i'm using archlinux 64
my code on 32 bits was using

$read = array($stream);
if (false === ($num_changed_streams = stream_select($read, $write = NULL, $except = NULL, 1,0))){

on 32 bits ok, it wait one second or if data received return with num_changed_stream>0

on 64 bits no, it return imediatly and num_changed_stream=0, since tcpdump didn't show nothing i think that's an 64bits bug

i created $stream with:

$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo, $this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
		stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);



Reproduce code:
---------------
<?
$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo, $this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
		stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);

$read = array($stream);
echo microtime(0)."\n";
$num_changed_streams = stream_select($read, $write = NULL, $except = NULL, 1,0);
echo microtime(0)."\n";

?>

Expected result:
----------------
a long time (1 second of diff)

Actual result:
--------------
on 32bits php ok 
on 64 bits php return .0010 seconds of diff and tcpdump didn't showed nothing on this stream

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
