You also need to be aware that the algorithm for AIX v3's malloc
is the same one used by BSD.  It uses "power of 2" allocation, which
causes requests to be rounded up to the next larger power of 2.  Thus,
for a 33MB request to be satisfied, you would have to have 64MB of
space remaining in your data segment.
