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