Not sure if it would be the best choice in this case, but there is also 
TLSF (Two-Level Segregate Fit), a bounded-time allocator useful in time- 
and/or resource-constrained systems. I used version 1.9 to manage 1 MB 
of RAM and it worked very well with Lua:

If you search the Lua-list archives looking for "tlsf" and my name, you 
should find a few precious hints I got from Luiz and/or Roberto.
