Hm, I'd like a way to avoid this boolean flag. As far as I can see you 
need a function that does two things:

* reflect tables

* send the database setup event

What if we just exposed reflectTables in megrok.rdb so you can call that 
directly? I'm trying to recall why DatabaseSetupEvent needs to be sent 
here, but I wonder whether we could move it somewhere else instead.

That just would feel slightly better to me than a boolean that changes 
the behavior.
