OK, but it doesn't sound very scalable.  What if two extensions
(assuming that's possible simultaneously) both have DBs, do we add 
extra fields to ggi_db_list ??  I'd prefer a tag-based approach (i.e.
buffer A belongs to library B).

Also, I thought whether extensions added directbuffers to the same list
(and same function calls) or whether they used their own list/function
calls was still an open question.  Did I miss something ?

Cheers,
