Matthew: The man pages I have for mmap(2) indicate that Linux is more than happy to throw SIGBUS if the underlying file has been deleted/truncated.

I think Rivo is right and that it's some kind of race condition, only I don't think it's due to threading, but instead due to reentrancy (different processes playing with the pixmap cache).
