I once was surprised to find a kernel developer tell me that the key
to portable 68K UNIX systems was only to rely on the contents of the
stack puke for determining, eg. what page had faulted, etc., never to
rely on MMU registers.
Of course, he was an inside-Motorola kernel developer.
Outside-Motorola developers tended to trust whatever MMU their
hardware had, because they could never get full docs on the stack
puke.

Propaganda:
UIUC runs the "ph" nameserver in conjunction with email. You can
reach me at many reasonable combinations of my name and nicknames,
including:
andrew-forsyth-glew@uiuc.edu
andy-glew@uiuc.edu
sticky-glue@uiuc.edu
and a few others. "ph" is a very nice thing which more USEnet
sites should use. There is an info-ph mailing list, or, contact
Steve-Dorner@uiuc.edu.
