(PECL event >= 1.2.6-beta)
EventBase::dispatch — Dispatch pending events
Wait for events to become active, and run their callbacks. The same as EventBase::loop() with no flags set.
Do NOT destroy the EventBase object as long as resources of the associated Event objects are not released. Otherwise, it will lead to unpredictable results!
