AsioExternalThreadEvent::unserialize() may legally throw PHP exceptions. When that happens, construction of PHP exceptions reenters VM, surprised flag is checked and pending C++ exceptions may be thrown. Let's make sure the queue of received events in runUntil() is not lost. Move this responsibility to the AsioExternalThreadEventQueue.
