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