Sure.  But your patches aren't checking one compilation unit, they're
checking every compilation unit in the objfile at once.  That's why
they found duplicates.  I don't think any one compilation unit will
have a duplicate.

Yeah, I think I could write some testcases that were affected by this,
but I'm not sure.  It's tricky because if something else causes the
full symtab to load, the problem won't appear.

Maybe there's some way we can avoid needing psymbols for types at all.
But I think we need to have a real design and some documentation for
it instead of just accidentally omitting them.
