great! Looks good to me. The whole allocator is a bit of a patchwork,
but we knew that: the optimizations are heuristics so there will always
be workloads where the linear search could trigger. (If someone replaces
the whole thing with some smart size and address indexed tree structure
it may work better, but i'm not holding my breath.)
This needs tons of testing though.
