On w32, we set Vquit_flag directly when Ctrl-G (quit_char) is pressed. This is done in the asyncronous key handling where the event gets put on the Lisp input queue, so it does not have to wait for the input queue to be polled.

What is the entry point for detecting the Ctrl-G (or any other user keyboard input), when a tight loop is running, such as (while t t)? Is the SIGIO signal handler used, or is W32 itself asynchronously calling something in w32fns.c or w32term.c on a second thread?
