Prior to this change, it's possible for m_wake_me_up_again to be used while it's in an uninitialized state from the exposed API. e.g. - Using SetEnable after construction would perform an uninitialized read. - Using PushEvent would perform an uninitialized read by way of operator |=. internally, an uninitialized read can happen if PullEventsInternal() is executed before other functions. Just to avoid the whole possibility of performing uninitialized reads, we just give the class member a default value of false.
