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