631 The SIGHUP signal does not exist on Windows and does not need to be handled.
633 Windows handles SIGFPE and SIGSEGV signals as expected.
635 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
636 cause a new thread to be spawned. This may well result in unexpected
637 behaviour by the single-threaded LyX.
639 SIGTERM signals will come only from another process actually sending
640 that signal using 'raise' in Windows' POSIX compatability layer. It will
641 not come from the general "terminate process" methods that everyone
642 actually uses (and which can't be trapped). Killing an app 'politely' on
643 Windows involves first sending a WM_CLOSE message, something that is
644 caught already by the Qt frontend.
