We've been labeling some events as happening "outside the event loop", to avoid Libevent starvation. This patch provides a cleaner mechanism to avoid that starvation. For background, the problem here is that Libevent only scans for new events once it has run all its active callbacks. So if the callbacks keep activating new callbacks, they could potentially starve Libevent indefinitely and keep it from ever checking for timed, socket, or signal events. To solve this, we add the ability to label some events as "post-loop". The rule for a "post-loop" event is that any events _it_ activates can only be run after libevent has re-scanned for new events at least once.
