808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

8362cc2d1d phkmalloc/3 
Various neat features added.  More documentation in the manpage.
If your machine has very little RAM, I guess that would be < 16M
these days :-(,  you may want to try this:
	ln -fs 'H<' /etc/malloc.conf
check the manpage.

3aeb7f1d49 Correct a bunch of man page cross references and generally 
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.

b965b1036f phkmalloc/2 
"zero' and 'junk' options to help find and diagnose malloc abuse.
EXTRA_SANITY defaults "junk" to on.
Don't dump the internal state, unless EXTRA_SANITY.
General code cleanup.
Error messages cleaned up a bit, more checking earlier.
EXTRA_SANITY is default at this time (just in case).
Performance (without EXTRA_SANITY) is better, beats gnumalloc in
both time & space most of the time:

SANITY is not an option anymore. (!!)

3f27b3de03 ``phkmalloc'' 
Performance is comparable to gnumalloc if you have sufficient RAM, and
it screams around it if you don't.
Compiled with "EXTRA_SANITY" until further notice.
see malloc.3 for more details.
