Expecting a significant performance hit on initial scan of a file when
.gdb_index/.debug_names is not present there.  But personally I do not think
that matters as such scanning without any index was always very slow, that is
what the index is there for.

I am leaving the fix and/or assignment of the fix up to Pedro.
