Is there a way to manage (especially list and kill) long-running PHP processes on a Windows 7 system set up with WAMP?

Every once in a while, I'll accidentally throw an infinite loop into a PHP process and want to kill it. Right now, all I can think to do is to restart all my WAMP services but sometimes the PHP processes manage to survive right through the restart, i.e., I still see them outputting to logs even after WAMP's restarted. And if the process isn't logging, then I have no way at all to know when/if it's been killed. Not to mention, this will wipe out everything I'm doing with WAMP, not just a single process.

I don't seem to see anything relevant in the Windows Task Manager, but maybe I'm missing something.
