I have nothing to add on the subject of whether certain existing hooks
could be called from more places.  I'll leave that to you folks.  It's
certainly the case that a hook of any name, old or new, is adequate if it's
called from the right places.

Ok.  I think I understand how to do that if it's the right way to go.
At the moment, I have working code by tweaking the SOLIB macro in tm-linux.h.
Until you all decide whether some existing hook should be called from
elsewhere or a new one added to all those places, I won't bother writing
code for either alternative.


Thanks,
