Description:
------------
If the priority queue of scheduled events is empty, the dispatch loop should terminate successfully. This bug might be related to the fact that event_have_events returns true even if there are no events. 

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

dl('event.so');

event_init();

// called when user hits ^C
function stop($sig) {
    global $s;
    echo "You got signal $sig. Descheduling event.\n";
    event_deschedule($s);
}

$s = event_handle_signal(2, 'stop');

event_schedule($s);

echo "Going into dispatch loop: at t= " . time() . "\n";
event_dispatch();

echo "all done\n";

?>


Expected result:
----------------
all done

program exits.

Actual result:
--------------
program remains stuck in the dispatch loop. "all done" is never reached.

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
