The null dereferencing problem flames should be directed both at Berkeley
and Ma Bell rather than us, both had the opportunity, but never bothered
to make page 0 inaccessable because of the work involved.  I heartily
agree the current situation is a crock, and would be first in line to
propose a new a.out type on the Vax with page 0 mapped out, but the fact
has been that both at MIT and inside DEC Suns are uncommon and were hard
for us to get access to.  (At Athena, VAXstations and RT/PC's are all of
the machines there are....). We have spent weeks of our time trying to make X
as portable as possible (I spent 3 days of the last week linting the V11
Xlib), and on the whole I think history has shown succeeded, but that is
the difference between a $100 source tape with no guarantees and supported
vendor code.  As a DEC employee working on Athena, it was my
responsibility to make the device independent code work on the VAX and the
RT, but not Sun, Apollo, IS, etc....  So please don't begrudge the vendors
some money for the supported versions; you do (often) get what you pay
for.  Many people have made major contributions from all directions; that
X runs (or occasionally limps) on the rediculously huge number of
machines/displays it does astounds me.

So please direct flames in the appropriate directions, and keep posting
the fixes (without flames....).		

And PLEASE make SURE you include the MIT release number and rcsid version
of the file from which you made your diffs!
