It isn't a patch, it's a stand-alone test program and should be pretty easy to follow. Honest! Brief summary: we grab the pid of a forked child process and then, every 500ms check its status. We use the timer (that has your name on it!) to emit the signal that is connected to the ForkedcallController::timer method. If a process is found to have finished, then we call it's callback function. Easy! Angus
