 711 Signals and Windows
 712 ===================
 713 The SIGHUP signal does not exist on Windows and does not need to be handled.
 714
 715 Windows handles SIGFPE and SIGSEGV signals as expected.
 716
 717 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 718 cause a new thread to be spawned. This may well result in unexpected
 719 behaviour by the single-threaded LyX.
 720
 721 SIGTERM signals will come only from another process actually sending
 722 that signal using 'raise' in Windows' POSIX compatability layer. It will
 723 not come from the general "terminate process" methods that everyone
 724 actually uses (and which can't be trapped). Killing an app 'politely' on
 725 Windows involves first sending a WM_CLOSE message, something that is
 726 caught already by the Qt frontend.
 727
 728 For more information see:
 729
 730 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
