    • No instance for (NFData a) arising from a use of ‘deepseq’
      Possible fix:
        add (NFData a) to the context of
          the type signature for:
            idle :: EngineState a -> MVar a -> IdleCallback
    • In a stmt of a 'do' block:
        deepseq newState (swapMVar mvarGs newState)

        do { gs <- readMVar mvarGs;
             secs <- getSeconds;
             let ms = toMilliSeconds secs
