[jira] Commented: (RVM-791) Clean up and modularize locking

Filip Pizlo commented on RVM-791:
---------------------------------

This looks cool!  I think it is orthogonal to my code - what I'm doing is looking at different ways of doing locking under the assumption that you have a ~20 bit (or whatever the object model gives me) "lock word", which I can then interpret as being a thin lock word, a biased lock word, or whatever.  I'll proceed undaunted for now, but at some point we may end up merging.

My thinking is you'd want one package to deal with the implementation of locking (what I'm doing), and another to deal with the representation of the lock word in the object model.  These can be orthogonal, and their interaction can be limited.  Agreed?
