The issue seems to stem from the fact that our dsound implementation includes a
winmm timer that sends a WM_TIMER every 10 ms.  Further, iTunes lolligags
a bit between posting it's TimerFired message and doing a GetMessage(),
which pretty much guarantees that a WM_TIMER will be in queue behind
the TimerFired message, which triggers the bug.
