The reason I didn't suggest that is that we don't have an
address space object --- yet.  My multi-exec patches add one, and
there's a similar mechanism to per-objfile data where we can
do things like these.  More than one inferior can share the
same address space, so we could share a cache between them, but,
if the cache if write-through, it won't be a big problem if we
don't ---  it would be if it was left as writeback.

I don't have a problem with adding this to struct inferior for now,
it just seemed premature.
