event_base_foreach_event() holds a lock on the event_base() for the whole
time it's running: slow callbacks are not advisable.
Note that Libevent adds some events of its own to make pieces of its
functionality work. You must not assume that the only events you'll
encounter will be the ones you added yourself.
The callback function must return 0 to continue iteration, or some other
integer to stop iterating.
