The window X button sends the "delete-event" to the window.  The default
handler for a delete event is simply to destroy the window.

What you are doing is killing the main loop in your quit handler.  This lets
the program run to completion, at which point both windows are destroyed and
cleaned up.  This isn't what you want it to do, obviously.  The second
window's "quit" should be a "close", and its handler should destroy the
window, not kill the main loop.
