 Ok, I believe I've fixed this now.

   * FIX #1198: hWaitForInput on Windows
   Now we do the appropriate magic in fdReady() to detect when there is
   real input available, as opposed to uninteresting console events.

   * Make threadWaitRead/threadWaitWrite partially useable on Windows

   They work with -threaded by calling fdReady() in a separate thread.

   "threadWaitRead 0" also works without -threaded (because we happen to
   know it's virtually equivalent to "hWaitForInput stdin (-1)").
