A cache that is a hybrid of the Memoizer in Listing 5.19 in Java Concurrency in Practice and https://www.bionicspirit.com/blog/2012/07/02/love-scala.html. Makes sure to put a Promise of the memoized value into the cache only if it's not already there. Then only compute the actual value (in a Future) and complete the Promise with the Future only if the promise was successfully inserted atomically. Otherwise, another promise was snuck in so use the Future associated with that Promise.
