Great!  I haven't had time to look closely at the details, but it seems
to eliminate some of the uglier parts of the original patch.

I tested this against LLNL's Cray pointer test suite (which we are
trying to make public; I'll check on the status) and everything works fine.

Yes, that's right.  I had originally added that conflict, but I think
that I took it out because blanket SAVEs were causing problems; it would
be better to do what you suggest.  In any case, SAVEing a pointee
shouldn't actually affect anything, since there isn't anything to SAVE.
