Can we move create a pool for these delegate threads? The default can be
empty but we'll expand as needed. We also need to think about interruptions and
errors. It might be better if the actual method interface is Future<Result> and
we allow the implementor pick when to block. Guava has a abstract checked
future that would probably solve most of these needs.
