By the way, since this is a monad, I think a better place than
Control.Concurrent.Forkable would be Control.Monad.Forkable.
It's just a suggestion.

>> type MyMonad = ReaderT Config (StateT Ctx IO)
>> startThread :: MyMonad ThreadId
>> startThread = forkIO threadMain
>> threadMain :: MyMonad ()
>> threadMain = forever $ liftIO $ putStrLn "Painless monad stack forking!"
>> Note the lack of monad stack deconstruction and reconstruction to

>> forkable-monad is available:
>> * On hackage: http://hackage.haskell.org/package/forkable-monad
>> * Via cabal: cabal install forkable-monad
>> * Source and issue tracker: http://code.google.com/p/forkable-monad/
>> Feedback is of course welcome. As this is my first published Haskell
>> code and Hackage upload, I expect there will be quite a bit!
