windows that wouldn't quit on demand, the app_server would have gotten the kShutdownServer message anyway already (as the last app was quit). Since that one removed things like gDesktop/gBitmapManager, it liked crashing. Now, there is a semaphore that will be send to each app on quit. Only when this semaphore can be acquired, the shutdown message will be sent. Removed unused semaphores (decorator, active app). Replaced fAppListLock with a BLocker (just calling acquire_sem() without error checking is very unsafe in userland, and should never be done). BTW the bug was triggered by broken menu code that only sometimes really quit the window; it leaves a whole lot of zombies around - Stefano, any quick idea? :-) git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13384 a95241bf-73f2-0310-859d-f6bbb57e9c96
