Nice work!  It may be preferable to store the pointer elsewhere however.  I
believe all blocks returned by the allocator must be 16 byte-aligned, so
tacking a pointer onto the end of a block either screws this up or uses up a
lot more space than necessary.  I also kind of wish that the pointer didn't
have to be stored at all for small block sizes, since simply storing the mask
itself would take up less space (admittedly, at the expense of more complicated
logic).
