It's a problem which is localized to you and caused by the specific
problems of your setup. This isn't a wide-spread problem at all and
the world doesn't revolve around you. If your setup is so messed up
as to require sticking to 16bit pids, handle that locally. If
something at larger scale eases that handling, you get lucky. If not,
it's *your* predicament to deal with. The rest of the world doesn't
exist to wipe your ass.
