It's very problematic. First off, collection often clears the young
generation altogether, promoting everything. Secondly, I think we are
already short of header bits in some cases. Thirdly, this requires
all collectors to be changed. Fourthy, some collectors don't use
multiple generations: they can just allow a dense prefix to pile up at
the left-hand end of the heap which they don't bother to collect.
