I've forgotten how timer interrupts inter act with OS level threads. 
However, maybe a simple hack is to just allocate some fixed number of OS 
threads that each multiplex MLton's current lightweight threads. I guess 
there needs to be some global locking and way for the GC to "work".

Oh, once I get my box.. I'll be looking for an excuse to play with the 
dual cores.. I was hoping to find an MLton related project.I guess, I 
should look at the web-server someone recently ported to MLton that 
looks like something an extra core would be good for. :)
