The tech stuff is over my head, but I do have three questions related to 
this:

1. What about Alien? Shouldn't we try to move towards Alien instead of 
current FFI? Or is that too much work at this point?

2. Callbacks has been a sore point in Squeak for a long time. AFAIK 
there is a patch available on www.squeakgtk.org/wiki/download.html, not 
sure what it does or if it is the original patch from Andreas when 
wxSqueak was being built. wxSqueak had a patched VM I recall. Perhaps 
that stuff is not related.

3. Could we possibly ask for a status update on Cog and related 
activities? We are itching for news! :) Also curious about your interest 
in Factor and its lower bowels (definitely cool stuff going on there).
