Hmmm... unload would be the bigger problem, I suppose.

I'd look at it this way -- this is really a subset of "debugging
separate processes".  The subset is, processes that share the same
symbol set.  What you suggest is crowding that boundary.   ;-)

We know that the set of programs that can be debugged this way
is prescribed.  Can't do multi-threaded programs, for instance.
