Jeremy (or someone vaguely like him, if there is such a thing) would need to
answer the performance and resource questions.  As for the [v]UIDs, they are
per connection.  Theoretically, if you and I each have separate connections
to the same server we could have the same UIDs in use.  They can be the same
because they exist in separate contexts.

How that is actually done is, of course, implementation specific.
