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