Unfortunately it isn't...it works correctly in R5 though. How is the
owner set up in a freshly constructed window? I notice _InitData sets
it to B_ERROR, and also sets fCachedStack to 0, so unless something
else is happening in between that I'm missing,  BLooper::check_lock
cannot possibly succeed.
