I'd expect the arguments of cancelWith to be the other way round.
Then you could say
cancel = cancelWith ThreadKilled
An alternative, equivalent interface for waitEither and friends would be
waitEither :: Async a -> Async a -> IO (Either SomeException a)
waitEitherThrow :: Async a -> Async a -> IO a
This might be conceptually simpler, leaving it to the user to decide
whether to mark the results with Left/Right, or something else, or not.
Similarly the Async now returned by waitAny and friends could be left
to the user. That would leave the two sets of functions more in line.
