Thanks, I've incorporated your Concurrently type, and renamed 
doConcurrently to mapConcurrently (by analogy with mapM).

I released async-2.0.1.0 with the latest round of changes:

http://hackage.haskell.org/package/async

Changes in 2.0.1.0:

     Added a Functor instance for Async

     Added asyncBound, asyncOn, asyncWithUnmask, asyncOnWithUnmask, 
withAsyncBound, withAsyncOn, withAsyncWithUnmask, withAsyncOnWithUnmask.

     Added mapConcurrently

     Added Concurrently (with Applicative and Alternative instances)

Cheers,
