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