 771 Signals and Windows
 772 ===================
 773 The SIGHUP signal does not exist on Windows and does not need to be handled.
 774
 775 Windows handles SIGFPE and SIGSEGV signals as expected.
 776
 777 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 778 cause a new thread to be spawned. This may well result in unexpected
 779 behaviour by the single-threaded LyX.
 780
 781 SIGTERM signals will come only from another process actually sending
 782 that signal using 'raise' in Windows' POSIX compatability layer. It will
 783 not come from the general "terminate process" methods that everyone
 784 actually uses (and which can't be trapped). Killing an app 'politely' on
 785 Windows involves first sending a WM_CLOSE message, something that is
 786 caught already by the Qt frontend.

 789
