Comment:
I've actually been intending to fix this a different way. I want to add
`forkFinally`:
{{{
forkFinally :: IO a -> (Either SomeException a -> IO ()) -> IO ThreadId
forkFinally action action =
mask $ \restore ->
forkIO $ try (restore action) >>= action
}}}
Furthermore I'd like to add an Async API that builds on this to add some
higher level concurrency operators, but I'll post a proposal on the
libraries list about this.
