Libevent - applications should now be more resilient to jumps forwards or backwards - in the system clock. Also, on Linux systems with epoll, we now - optionally support microsecond-level timeouts (whereas epoll only - supports millisecond-precision timeouts). - - o Use mach_absolute_time() for monotonic clock support on OSX.

Now deferred events no longer cause priority - inversion, no longer require special code to cancel them, and so on. - - o Refactor the callback part of an event into its own event_callback - type (cba59e5) - o Add "active later" event_callbacks to supersede deferred (745a63d) - o event_base_assert_ok: check value of event_active_count for - correctness (fec8bae) - o Replace deferred_cbs with event_callback-based implementation.
