Ian was using the mtmalloc for .29 and the standard malloc library
for .32.  You'd want to use mtmalloc for MP machines.  As we've seen
in practice, we're severely limited by the efficiency of the malloc()
implementation due to the buckets not being freelist'd.  So, using
special-purpose malloc()-implementations help tremendously.
