Yeah.  I was thinking of perhaps splitting objfile in two, and moving
the relocated bits into a per-inferior handle, which points to the
abstract objfile.

But, this is just a vague thought.  And, we've been talking a bit in
Archer-land about some more drastic changes to the symbol tables
(e.g., getting rid of psymtabs for dwarf), and this would probably
interact with that as well.
