- Send a cancellation request to display event thread before waiting for it join. This thread waits for poll to return indefinitely which may not return if all of the events (vsync etc) are in disabled state. - Drop this call for Android for now as this api is not supported in bionic. - Fix GetVSyncState return value. - Fix pwrite return value in case of set on idle time out.
