Comment (by rwbarton):

 Since this is on Windows, I wouldn't put it past the console to do this
 whenever the terminal is in cooked mode (or Windows equivalent). Maybe you
 just want `hSetBuffering stdin NoBuffering`? That would put the terminal
 in raw mode on non-Windows systems, but apparently it doesn't work on
 Windows, see #2189.
