Thanks Eli.  I hadn't gotten around to examining those comments in
detail.  In general I was OK with what I read with one exception: I'm
not so excited about adding a new pointer to the file structure, which
is an extra 8 bytes (on 64bit hardware) for every file struct for the
rare situation that the file represents a loaded shared object.  Make
already uses far too much memory, IMO.

I would prefer to do something like use a boolean bit in the file object
to specify that it refers to a shared object, and keep the pointers in a
different structure.  Then if the bit is set we can take the hit of
looking up the pointer; this will be very rare anyway.

I can look into this more this weekend.
