Description:
------------
sleep() does not work as it did before...

sleep() now only seems to work up to a certain number of seconds, I haven't figured what that number is. But if this now how sleep() will work in PHP, could you please add the maximum value, (number of seconds allowed to be used in sleep()) to the manual.

Reproduce code:
---------------
<?

// some ridiculous amount of time..

sleep ( 63166608000 );

?>

Expected result:
----------------
script should sleep...

Actual result:
--------------
script continues without sleeping, and triggers a warning, that makes no sense at all.

PHP 5.1.3 and in older versions, sleep() would sleep, no matter how many seconds were used! snaps.php.net (5.2.dev-latest, 6.0-dev-latest) also seem to follow version 5.1.3 and older version, sleeping no matter how many seconds are used in sleep()!
