+ /* Android's NativeActivity relies on a Looper/ALooper object to
+ notify about events. The Looper object is plugged on two
+ internal pipe(2)s to detect system and input events. Sadly you

+ there is a pending event (and process it later). Consequently,
+ short of redesigning NativeActivity, we cannot
+ SleepForEvents. */
