Userland threads can contend against themselves, right now the kernel
doesn't but it would be a good thing to implement for later use.
We also support shared address space fork, so this may be a good idea
for programs that utilize that.
This allocator is pretty much what the Dynix allocator is, it wouldn't be
difficult to clean-room implement this with a BSD license.
They should have given credit to Dynix or at least Uresh Vahalia
(discussed on page 390 of his book Unix Internals section 12.9).
