Actually, I was proposing XMAGIC as an optional alternative to
ZMAGIC, not as a replacement for it.  We want XMAGIC to aid debugging
of locally-written programs.  I don't have the time to fix all of the
poorly-written utilities that try to reference through zero.  By
continuing to use ZMAGIC as the default I can sidestep the issue to
some extent.

Of course, any library routines which expect references through
(foo *)0 to work will need to be modified.  Does anyone have a feel
for the number of routines that may need modification?
