* This is a trick to prevent the foreground thread from being delayed.

* it keeps running and locking again it can prevent the main thread from
* acquiring its lock for a long time... sometimes even > 5 seconds
* (leading to an ANR).
*
* Dalvik will promote a monitor to a "real" lock if it detects enough
* contention on it. It doesn't figure this out fast enough for us
* here, though, so this little trick will force it to turn into a real
