The memory eater strikes back (2nd attempt to get attention)

About SGI's and memory leakage:

Something to remember is that the SGI graphical object library has
memory leaks.  This is a random fact that I ran into which I though
some people might be interested in.

The libc malloc slows considerably when dealing with many small object
allocations and deallocations (typically a few hundred thousand if I
remember right) where the BSD malloc degrades "reasonably"; pooled
allocations will improve performance dramatically if you are doing
this type of allocation on the SGI.

The libmalloc malloc, even if broken, is good to run some tests with
because it smashes the malloc'ed area; we found many bugs because of
this behavior (and even more when running on a machine which
disallowed null pointer dereferencing :-).
