That would mean having special case code in every module, instead of
having the special case code in only one place. I think that would be
very hard to maintain.

If we decide to go ahead with this module chaining approach we can
expose ldb_load_modules_list() or an equivalent function via

For now I want to get the basic model right. For that I suspect I'm
going to need some input from Metze, as I'm not really sure exactly
what modules we do/don't want exposed to the DRS replication requests.
