Unless Robin disagrees(?), I would say that 2 and 3 have evolved into a
single merged proposal that comes with various minor variations for
different collection needs: simple "stop the world" (stw), generational
stw, concurrent, etc.  You could call it the "epoch-based vtable
marking" approach.

So, that bring us back to 3.

Robin: Do you agree?  :-)
