XMAGIC: a.out without a valid page 0?

[guy at rlgvax.UUCP]

So, according to an authoritative source, did a paging VAX-11 UNIX done
at BTL.  I don't think "well, it'll break lots of existing - but *incorrect* -
UNIX programs" is necessarily a reason to do something.  Correctly written
C programs have no problems with dereferencing null pointers (remember,
according to K&R, a null pointer doesn't point to anything).
