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