  o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec
  o New event_base_got_exit() and event_base_got_break() functions to tell whether an event loop exited because of an event_base_loopexit() or an event_base_loopbreak().  Patch from Ka-Hing Cheung.
  o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change.
+ o Fix some bugs when using the old evdns interfaces to initialize the evdns module.
