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