Comment (by viboes):

 I believe this is a bug.

 When you launch the continuation with deferred policy, the continuation
 shouldn't be executed until a call to result.get() is done.

 Actually the future.then(launch::deferred, f) do a call to future.wait()
 and so it blocks.

 I will try to fix it for the next release, but the release is upcoming :(
