Hmm, it was quite useful when implementing SPU overlay support
(see the patch set I just sent out).  I'm using it to attach
a target-specific overlay table data structure to each objfile
as it is read in.

There didn't seem to be any other callback that was just right
for this (e.g. executable_changed is called already before the
symfile_objfile is instantiated) ...

Any suggestions how to solve this differently?

Thanks,
Ulrich
