You don't set the site managers as a site, but the objects that are
sites have site managers (or "component registries") attached to them.

Also, the global registry is always "active", without settinga site.

You'd have to open a connection to the database, get the root object and
use that with setSite(). I don't have the complete spelling for that in
my head though. If this is code that runs within Zope 3, then you might
not want to talk to the database directly anyway because of the
automatic transaction management.
