It should get cleaned up when the window is closed. Closing a toplevel
window causes its destroy signal handler to fire. The destroy signal
tells the window to "break references" to other objects. Among other
things, this should disconnect all of its signal handlers. I wouldn't
be surprised if there are still some reference loops though.
