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