If I am correct, well, "perhaps" I have something that just might be able
to
help your allocator. There is an invention that can transform most
single-threaded memory allocators into scaleable multi-threaded ones; here
is my initial post:

http://groups.google.com/group/comp.arch/browse_frm/thread/6dc825ec9999d3a8

basically, you create single-threaded allocator and plug it into the
system,
then, boom, its multi-threaded. If you have any questions, feel free to
fire
away...
