runOnAndroidMainThread(): Don't block QThreadPool::globalInstance() with timout awaiters
A waiting task on QThreadPool::globalInstance() will block the worker
thread that it was scheduled on, making it unavailable for productive
work. That's why one should only put CPU-bound tasks onto
QThreadPool::globalInstance(). When blocking nonetheless, use the
releaseThread()/reserveThread() trick to avoid deadlocks caused by the
pool running out of workers.
So, do that here.
