Comment(by AndreasVoellmy):
The last patch addresses the previous comment by igloo. I made the
threadWaitSTM return an IO action that unregisters interest in the file
descriptor. By returning an `IO ()` value we avoid having to export the
`FdKey` type and `unregsterFd` functions.
I also added some haddock comments to `threadWaitReadSTM` and
`threadWaitWriteSTM`.
