FWIW, I see comments in vd_realvid.c that tries to patch away multithreaded
code for RV40, but seemingly only on Windows. No such thing for RV30, and
the RV30 Windows DLL has a single call to _beginthreadex (a CRT function we
do not emulate...) that calls a dummy function, and never seems to use
threading apart from that.
I'm willing to contend that if this was a problem, it was only a problem with
RV40, and if so, I can't reproduce it anymore here.
