    Arg. It looks like I must have added another few instructions
    somewhere, and triggered the same size-increase that I talked
    about in the "Adventures with gcc: code vs object-code size"
    thread on the freebsd-hackers. In that case, adding 40 bytes
    of new instructions to one routine in ps.o caused /bin/ps to
    jump by 3940 bytes.

    As long as I had avoided whatever that threshold was, I was
    able to keep the size down around 27000 bytes. And that was
    for a version which *included* the -R, -s, and new -g options.
    Man that's annoying, I had been doing so good with it...
