---------------------------------------------------------------------

One concept that I think I should point is how getAsync improves performance is 
that if the value is not available immediately, then the client can cache the 
future and work on other keys. Look at the implementations of AbstractDeduper. 

1. If SpillableArrayListMultimap only lacks asynchronous get, then that can be 
added to it. That should not be the only reason to duplicate the functionality.

2. ManagedTimeMultiValueState has no tests and is full of warnings.

We should not create a complete separate implementation which duplicates a 
larger part of functionality provided by something existing otherwise we will 
have too many slightly different variations of the same thing and that will be 
very difficult to manage. 

IMO this is a good opportunity to improve SpillableArrayListMultimapImpl and 
use that.
