5227 :: Read Stdin asynchronously

  The Nim in Action says that reading from stdin via asyncfile is not supported. I wonder if that is still true now?

  IIRC it depends on the OS.

  https://github.com/nim-lang/Nim/issues/11564 Seems only works on Linux.

  Maybe this is unrelated... but are you making console chat?

  I did a really stupid work around where I would read from stdin with "getch" in a different thread and poll for it in the main thread.

  I did this so that i could have console chat. So as you type messages other messages could come in front of what you where typing. This requires erasing what you are typing, printing the new message, putting what you where typing and putting the cursor back.

  The workaround outlined in Nim in Action is still the best way to achieve this in a cross-platform fashion. That is until we are able to await a FlowVar, once that is implemented and working it'll be the same idea but the code to achieve will be much shorter and far more efficient.
