Fair enough. WRT dense allocation, we could probably do a lot better if
we allocated some N nodes at a time rather than one at a time on demand
when the freelist is empty. When we allocate those N nodes, obviously
N-1 go onto the freelist.
It'd be interesting to see the cache effects of doing something like
that ;-)
