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

89e3b80fa2 Fix a very rare error condition: The code to free VM back to the kernel
as done after a quasi-recursive call to free() had modified what we
thought we knew about the last chunk of pages.
This bug manifested itself when I did a "make obj" from src/usr.sbin/lpr,
then make would coredump in the lpd directory.

b487e9d356 Submitted by: (based on code in "Advanced Programming in the Unix Environment"
by W.Richard Ste vens. EINTR handling suggested by bde@freebsd.org).

Code cleanup:

1. Add missing return type.
2. Replace 'union wait' by int.
3. Use Posix-style signal handling instead of signal().
4. Use fork() instead of deprecated vfork().
5. Block signals before fork()'ing, instead of after.
6. Return -1 if fork() fails, instead of 0.
7. Add EINTR handling for waitpid() call.

Also add claim of Posix conformance to man page.

04936d2e08 Change phkmalloc so that the page directory is now floating and allocated
via mmap() up around the shared library area.  Previously the directory
was allocated from space from it's own memory pool.  Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.)  I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)

I've been running this in my libc for about a month...

Also, seperate MALLOC_STATS from EXTRA_SANITY..  I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-)  I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.

"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:

81df7b69ef ``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.
