Hmm. Half the problem is it happens in a completely non-deterministic 
fashion. The only thing you can hope to do is add some basic thread 
synchronisation to the code that deals with the file handle, From what I 
have experienced, there is no single way to cause this problem to 
reproduce.

That's my experience, too.  It seems to arise most reliabily if there's a
parse error when there's a main scene file calling macros in an include
file -- but I can't say if that's really a symptom, or if it's just that
most of my code lives in other files.

Sometimes it just happens -- even if the parse is over and had no errors.
