Maybe you can use kbhit() and getch() from msvcrt.dll

kbhit returns whether there are any keystrokes in the buffer
getc returns them.

So, what I do is (or something similar, I don't have the exact code here):

kbhit = Win32API.new('msvcrt','kbhit',...)
getch = ...

def wait_for_keypress
  while true
    if kbhit.Call
      ch = getch.Call while kbhit.Call # to flush the buffer
      return
    end
    sleep 0.1 # this should allow other threads to run
  end
end
