I think you should replace gmalloc.c with the Doug Lea (current
glibc-ish) version, which supports using mmap.  I think I sent changes
for that long ago; I don't remember what the objection was, but I
don't think I was convinced by it.  It also helps with not filling up
the Emacs pointer address space in the implementations I've seen,
where mmapped addresses come from the other end of the system address
space.

As far as I remember, Solaris is the major platform where mmap isn't
used for buffer allocation now.

Regarding the original complaint, I guess I'm not greatly concerned if
I can turn the feature off and it won't affect most users as Stefan
explained.
