be983aacdf extract read_upgrade into a separate helper 
And use it from `maybe_changed_since` where it makes sense.

2ba9c97815 rewrite to thread a Vec<Receiver> to signal waiters 
This is both more precise and the logic is simpler.

00c76be635 refactor derived read to only require read lock 
The old setup acquired `upgradable_read` even when the value was cached.
At that point you might as well just a mutex.

Niko Matsakis
2d6e454638 add the idea of "untracked reads" and use it to optimize volatile 
Now we won't be tracking the inputs to a volatile query, since we don't
care about them anyway.
