Qemu's implementation of one of the timer chips is wrong
(or at least, was wrong a couple of years ago). See
<http://mail-index.netbsd.org/port-i386/2005/08/06/0003.html>.
If you set the timeout to be much larger (at least thousands of seconds,
possibly tens of thousands of seconds), then it should count down slowly
enough for you to press a key.
