I did a quick check, and it seems the whole ruby C interpreter isn't  
thread safe.
(LUA is, btw. :-).

So, we need to make sure that ruby is called only from one thread at  
a time. This makes the threading thing a lot more difficult, I guess.

At least, now I'm more unhappy about the initial choice of taking  
ruby... :-( but back at the time we started, LUA wasn't that far  
developed, if I remember correctly (I know that we talked about it).

cheers
