Unfortunately, I *need* the ability to have both:
$obj->method()
and
$obj->{KEY} # Routed through __PACKAGE__::FETCH
work.
Some users are served by just the hash-access to the RPM database. But some
need the greater functionality, and it becomes even more of an issue with
the RPM::Header class, where there are a lot more non-hash-specific methods
to contend with, as well as the need for FETCH et al to behave in a tied
manner.

This is the first real problem I've run into, and it *seems* to stem from
the fact that the underlying object which $obj is a reference to (the PVHV)
has a REFCNT of 2, according to Devel::Peek.

Yeah yeah, and as we say at science fiction conventions around here,
"Captain Kirk, Mr. Spock, and Ensign Red-Shirt beam down to the planet
surface. Which one isn't coming back?"
I will take a look at this. My code is that dependant on it. But I also
need a band-aid solution, since any patch I come up with would be months
(at best) from making it into distribution versions of Perl (not just Red
Hat's, but Mandrake and others).
