 683 Signals and Windows
 684 ===================
 685 The SIGHUP signal does not exist on Windows and does not need to be handled.
 686
 687 Windows handles SIGFPE and SIGSEGV signals as expected.
 688
 689 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 690 cause a new thread to be spawned. This may well result in unexpected
 691 behaviour by the single-threaded LyX.
 692
 693 SIGTERM signals will come only from another process actually sending
 694 that signal using 'raise' in Windows' POSIX compatability layer. It will
 695 not come from the general "terminate process" methods that everyone
 696 actually uses (and which can't be trapped). Killing an app 'politely' on
 697 Windows involves first sending a WM_CLOSE message, something that is
 698 caught already by the Qt frontend.
 699
 700 For more information see:
 701
 702 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
