Just clearing out some of my message storage, and thought I would
resend the following, originally dated 2002-04-12.  Please ignore
the mount on delorie.com (which could well be removed if it is
still there) and use the mount on my site.

I still don't know if anyone has found anything either good or bad
about it.

I also have it mounted (no ftp) at:

    <http://cbfalconer.home.att.net/download/nmalloc.zip>

with the slight addition of "evilalgo.c" which shows up other
failings in the present library code to do with realloc.  Please
see my message in the mailing list/newsgroup which has ab
comparisons.

This shows that a major improvement is available, a factor of 2 to
4 in speed, and (on my machine at least) a factor of 4 in
available memory usage.

The realloc performance is, to my mind, quite serious.  So I am
once again urging people to take a good look and possibly
incorporate it in 2.04.
