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