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