But that is the part I'm curious about. I've been reading up on some vm 
inlining techniques and wondering which ones might be added to YARV (I'm 
reading the items recommended in the Strongtalk "syllubus", see 
http://groups-beta.google.com/group/strongtalk-general/browse_frm/thread/83bda45b670b5a5b?tvc=1). 


I couldn't find anything on the web about unification until today -- 
"superinstructions" from VMGen. I will try to find some info on that.

Thanks.
