It's my impression that to have a system-wide cross-language GC, the 
languages
would all have to agree to follow certain conventions at runtime, such 
as rules
about which registers are used for what purpose at all times, and about 
conventions for
telling the GC when it can roll back the PC in certain ways, etc.. If 
so, that's a more stringent
requirement that's hard to meet in these days of mix-and-match software.
Olin Shivers, can you comment?
