Right, that's the idea. Otherwise, it'll tell you that the key has
expired (or otherwise gone missing) or that it's changed since you
last looked at it.
gets gives you both the value and the value identifier at the same
time (otherwise, there wouldn't be much of a point).
The regular get operation(s) could potentially return the same
thing, but it would require protocol extensions that may confuse
clients in the ascii protocol, and would definitely do so in the
