If we don't need the static heap, then let's ditch it. If we do need it, then 
let's have our own allocator (named emalloc, say), which uses the static heap 
and/or the system malloc as needed. Regardless, we shouldn't be trying to 
redefine 'malloc', nor should we be supplying our own allocator merely because 
that was a good idea back in 1989.
