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