562 The SIGHUP signal does not exist on Windows and does not need to be handled.
564 Windows handles SIGFPE and SIGSEGV signals as expected.
566 Ctrl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
567 cause a new thread to be spawned. This may well result in unexpected
568 behaviour by the single-threaded LyX.
570 SIGTERM signals will come only from another process actually sending
571 that signal using 'raise' in Windows' POSIX compatability layer. It will
572 not come from the general "terminate process" methods that everyone
573 actually uses (and which can't be trapped). Killing an app 'politely' on
574 Windows involves first sending a WM_CLOSE message, something that is
575 caught already by the Qt frontend.
