I would have though it would be when the enginefacade is created, which
I suspect happens at load time. However, perhaps the plugin bit doesn't
occur until the first connection is made, where it needs to use the
URL. Not sure. In nova, that would happen at startup time too, but
probably not glance.

Yeah, your confirmation that we've loaded it multiple times before rules
out the ordering thing (as I expected) but maybe it rules back in it
being something specific to glance.

Maybe we should ping zzzeek to look.
