Using rb-readline in Windows with cygwin/mintty/git for Windows doesn't work

The cause seems to be the rb-readline gem, which uses the Win32API:

    @kbhit = Win32API.new("msvcrt", "_kbhit", [], 'I')
[...]
      while (@kbhit.Call == 0)
        # If there is no input, yield the processor for other threads
        sleep(@_keyboard_input_timeout)
      end

kbhit seems to never register the keypresses when using Cygwin or miinTTY, so the rb-readline gem is always in sleep mode.

Seems to be an old problem, see here (from 2012):
