No one I know of is working on it. The code has changed a lot since 2.4
and in some ways it's a little non-trivial to bring across.
When I last looked at it I figured there are probably two approaches
* integrate it into the power-of-2 allocator and have the two work
together so you have a fast power of 2 for small allocations and a
slow "non-power-of-2" for large allocations.
* clean up the memory allocation subsystem so it can be replaced
allowing many different solutions, and a much smaller/simpler system
