    NetBSD has it in the base system. OpenBSD will soon have it in
    their base system. Solaris has it in their base system. My
    installs of Redhat 7.3 have it, although I'm not sure if that is
    in the base system or some rpm that we (@RPI) add...

    One nice thing about this is that the different OS's would have
    the EXACT SAME options for these commands, as opposed to `ps'
    where it's almost hopeless that we'll ever be able to sort out
    the different options on different OS's.

    I agree that it would be a good idea to implement killall as a
    special-case of pkill. It might take me awhile to do this, but
    I'm all for the idea.
