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