You can use future and promise to pass asynchronous values, true. But still,
its primary use is with threads. Things like async() and future.then() use
threads to carry out actions. Even if you don't use these features, you can
still use futures from Boost.Thread.

Note that I'm not saying there's no point in loosening this dependency of
futures on threads. I'm saying that Boost.Sync doesn't look like a proper
place for futures.
