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