--- Comment #4 from Anton Romanov <theli.ua at gmail.com> ---
It looks like BaseRenderer_InputPin_EndOfStream enters critical section
filter.csFilter, then calls BaseInputPinImpl_EndOfStream to handle end of
stream

that in turn goes down to DSoundRender_HandleEndOfStream
which has a tight loop to leaveCS , wait for This->blocked for 10ms and lock it
again until positions match :-/

It feels like that IS some kind of deadlock prevention, however it seems it
doesn't quite work right.

Though it may explain why eventually it sometimes unlocks itself
