>From Remi Moreover, are you sure the code that contains these callsites is JITed,
No, but then how would I know and what would I do if I did know. If its JITed and I do the 10th ( or whatever) invalidate in three months because of uploading a patch and because of that the app slows down until I reboot it that is a problem for me. Smalltalk is dynamic not just in its use of variables but in its ability to redo methods on the fly ( and create new classes on demand etc). Because of this I will need to invalidate callsites in the cache. I really don't think it will be helpful if I have to drop the methods and recompile the byte codes to get 'fresh' callsites. Maybe I could have a way to put the site back into 'bootstrap' mode. Maybe even with a SwitchPoint. I think I can deal with depth control I am not sure I can deal with an 'helpful' compiler regards mark
