Sounds interesting again :)

Recording mem-access patterns is a performance-oriented task, am I

How do you think, should patterns depend on certain JIT and GC
tightly? I suspect they depend heavily on GC, and not-so-much on
JIT. Though, I should say that JET uses a very cheap register
allocation mechanism, so it should negatively influence on the number
of memory accesses, and heavily. If you are more oriented on
performance you should be rather using OPT for that. But, yet, I do
not mind if you start with a more easy-to-use JET :)

Are you trying to implement some known techniques or is your work a
subject of ongoing research? What papers can I read on this to be more
acquainted with what you are doing?
