> HS2 calls SessionState.start multiple times (acquire, operation.run) - where
> it really just cares that the session is set in the thread local store. There
> are some calls in start session method now that preload stuff that's used
> during the session. Instead of doing that over and over again, I think it'd
> be nicer for HS2 to start a session once and then just do the thread local
> magic as needed.
