[haiku-development] BLooper::IsLocked()

Hi,

I've had a crash when quitting an app with an offscreen bitmap. The BBitmap 
destructor calls fWindow->Lock(); delete fWindow. The crash was in the 
BLooper::IsMessageWaiting() called from the destructor because the 
AssertLock() call failed. But the destructor called Lock() on top of what 
the BBitmap destructor did, so I think the looper was not in the global 
looper list (and then IsLocked() returns false). This looper has never been 
run either. Should IsLocked() simply test the fTerminating flag and then 
proceed to the fOwner based check?

Best regards,
-Stephan
