That does /not/ sound good at all.
It indicates that for some reason the boost threads library doesn't work
There is no way this can be fixed in POV-Ray itself (short of using a
different multithreading library, which would be a major undertaking),
and the only thing you as a user can do about it (short of reporting the
problem to the boost developers and waiting for a fix) is minimizing the
probability that thread synchronization issues arise.
The most thread synchronization heavy component of POV-Ray is the
radiosity sample cache. If you're using radiosity and don't want to do
without, you might want to try UberPOV and its no_cache feature.
