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