[Bug 28023] CoreAudio queue memory leak

http://bugs.winehq.org/show_bug.cgi?id=28023

--- Comment #6 from Jörg Höhle  2012-01-18 16:18:48 CST ---
When I'll be back at my Mac, I'll investigate whether the cause of deadlocks
truly is OSSpinLock in ca_in/out_buffer_cb.
Then I'll switch to InterlockedPushEntrySList (OSAtomicFifoDequeue is only in
MacOS 10.7) and use EnterCriticalSection for the rest of the code.

Any other idea?

This would also get rid of the anti-pattern IMHO
    OSSpinLockUnlock(&This->lock);
    sc = AudioQueueFlush(This->aqueue);
Readers of wine-devel will remember that I've criticized use of mid-function
LeaveCS; Wait; EnterCS.  Don't release a lock mid-way.
