558 The SIGHUP signal does not exist on Windows and does not need to be handled.
560 Windows handles SIGFPE and SIGSEGV signals as expected.
562 Ctrl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
563 cause a new thread to be spawned. This may well result in unexpected
564 behaviour by the single-threaded LyX.
566 SIGTERM signals will come only from another process actually sending
567 that signal using 'raise' in Windows' POSIX compatability layer. It will
568 not come from the general "terminate process" methods that everyone
569 actually uses (and which can't be trapped). Killing an app 'politely' on
570 Windows involves first sending a WM_CLOSE message, something that is
571 caught already by the Qt frontend.
