 Hmm, this is starting to sound like its pretty easy
to do. I think I might start playing with it. 

There would probably be a number of things to base
preembtion on. In erlang, I believe they base it on
the number of reductions, they may do the same thing
in mozart. You could also base it on some arbitrary
length of time as well. In fact, if the vm doesn't
collect some runtime stats this may be the only thing
to use. Does the vm collect any of these type of
stats?

  Hmm, I may have to look into this too. 

Overall it looks like it may not be to hard to provide
an 'Active Objects' (as mozart-oz calls them) in
squeak. I need to look deeper into the protoobject to
see how method dispatching can be preempted.
