Such regions may indeed need GC, though it's at least a very fast, generational-style GC that does not have to consider pointers from tenured space to new space.
... What is the difference between this and young generation scavenge? Seems the same to me. To me it seems we are discussing (a) statically sized regions... Which are already handled well by the stack, and (b) dynamic regions which need GC that are already handled well by young generation scavenge. If objects are being tenured too fast..We can prevent promotion for objects/regions only referenced by stack frames. What region win am I missing?
