Hey, Jay, not so fast there!

The REAL Vax, that is, Vax+VMS, does absolutely the right thing here.  It
maps data page zero out of virtual memory so that almost all attempts
to dereference a null pointer crash at once.

If you must pillory in public the people who tried to make *0 = 0, I will
line up right behind you with an armful of dead cats.  But please make sure
you have the right people.
