Description:
------------
using the stream_socket_recvfrom function in php 5.0.3 seems to leak memory.

my php is running with php.ini-recommended with the only changes being
report_zend_debug = on
display_errors = on

=== output of php -i ===

        stream_set_blocking($sp, false);
        while (true){
                $gtCheck = stream_socket_recvfrom($sp, 1500);
                echo 'loop = '.$count++."\n";
        }
?>
