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