Instead of having an annoying loop that constantly reschedules a Core::EventLoop trigger, have the ALooperEventLoopManager do it itself in the did_post_event() function. We cannot simply re-use the Unix implementation directly because that implementation expects to actually be called all the time in order to service timers. If you don't call its' pump() method, timers do not get triggered. So, we do still need the seconary thread for Timers that was added earlier.
