This is largely a solved problem (via objfiles).
See my dlclose() patch:
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00454.html
especially the call to free_objfile.
Or for another example look at clear_solib which works one struct
so_list at a time.
There are a few loose ends in freeing, but it is the tangled logic in
find_solib that is tripping us up more than the freeing.
