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