They also don't have protected memory across their threads, which makes 
Stackless less interesting IMHO (compared to, say, the Erlang model). 
Actually I guess these are similar issues, as the shared memory is why 
the GIL gets invoked so much, which kills the multicore stuff.

That said, apparently people do some really fast stuff with Stackless. 
That EVwhatever MMORPG uses Stackless a lot, for instance.
