Mats, if you're serious about this, do yourself a big favour and talk to
Eliot Miranda about his recent (as in a year or so ago) improvements to
block handling in VW; he's explained it to me but I couldn't for the
life of me explain it to you and get it right. Basically I think it ...
oh hell, get him to explain it.

And don't forget to talk with Ian Piumarta to make sure he isn't
duplicating the work (he said at ECOOP he'd tackle it soon) and that you
don't do anything that will break the jitter. Craig Latta did some
pretty serious planning with Ian some time ago on this subject so he
might some useful input for you as well. And don't forget the VM changes
you'll need.

And don't forget to work out howto get there from here; the bit that has
always put me off trying anything. I'd suggest using the SystemTracer to
clone a new image with BlockClosures rather than trying to manage with
both styles. At least with Squeak you can simulate the new system and
have a decent debugger.
