possible MCI deadlock

[Damjan Jovanovic]

I've been looking at bug 3930
(http://bugs.winehq.org/show_bug.cgi?id=3930), where
Heroes of might and magic basically hangs on a black
screen when sound is enabled (and works when sound is
disabled).

It happens on all wine versions, the winedbg session
below is from wine 0.9.11 and was done during the
black screen. Any ideas? What's exception c0000005?
