I did spend some time last year trying to get the primitives working in
trunk Interpreter, but I was a bit out of my depth and did not get it right.

Reminder and background info is on Mantis at http://bugs.squeak.org/view.php?id=7746

As far as putting the profiler into trunk, I should think that there would
be some way to have more than one profiler, and fall back to the old one
if the VM does not provide the needed support for AndreasSystemProfiler.

This seems like a worthwhile thing to do. Anyone care to take it on?
