Not the one induced by the Windows 'X' button: that one kills your
virtual DOS machine ("VDM"), i.e. it doesn't even try to talk to your
running DOS program.  That's why you get a warning dialog if you use
it ("Windows cannot shut down this program...") in essentially all
situations but one: when command.com is idling on the command line
(sometimes it takes a 'cls' for Windows to recognize this state).
