Actually, Sun made the fixes and gave them back to Berkeley, to help
all the other poor slobs who started with 4.xBSD as a porting base.
Berkeley was very good about taking these fixes back.  If/when we get
a line into AT&T, we will give them the fixes too.  I hope they will
also be willing to take back such fixes.  I strongly urge both Berkeley
and AT&T to build their systems such that access to location zero causes
a fault, and then fix all the bugs that turn up.
