Fortress, eh?  Never heard of it...

Actually, there's a couple of languages you could use on that machine
that are far, far from beta.

Your best bet for that machine is LUA at this point in time.  LUA is
multi-thread ready and pretty stable.  As long as you don't do any OO
and blink a little, Lua's syntax looks like Ruby.
Nowhere near as nice to do OO in it as in Ruby (or Python, for that
matter), but doable.  It is a tiny little bit nicer than Perl's OO (but
not by much).

And good old and somewhat dusty TCL has always been thread friendly.
TCL's OO is kind of a big mess, as it is not native to the language and
there are 2 or 3 frameworks for doing so.  However, TCL's big plus is
that it has been around the block for a long, long time.
