I'm not sure that I understand what you're doing here by creating
virtual hosts on the fly, do you mean in real time to the database of
virtual hosts updating - that would perhaps be a lot of work that isn't
normally required during the request, why not signal the apache server
to reload it's config when the db changes?
Are you doing this to save memory? Maybe mod_safeinclude would be of
some use to you, which does populate virtual hosts from a DB.
