Yeah, gnu's gdb also did this, It would be nice to have a full database
that supported the 2 levels, but gdb/db will work in a pinch.
This of course poses the question, how can we easially make the base
library support cases were the entire list is in memory and were only the
items that are required are loaded..
If we simply load the database in full each time we fire up then it won't
help anything at all.. Ideally progams like dpkg will only read the
package descriptions that they absolutely require..
Hm, I have some ideas on how to do that elagantly, I will have to ponder
them somemore before they are presentable.
