 767 Signals and Windows
 768 ===================
 769 The SIGHUP signal does not exist on Windows and does not need to be handled.
 770
 771 Windows handles SIGFPE and SIGSEGV signals as expected.
 772
 773 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 774 cause a new thread to be spawned. This may well result in unexpected
 775 behaviour by the single-threaded LyX.
 776
 777 SIGTERM signals will come only from another process actually sending
 778 that signal using 'raise' in Windows' POSIX compatability layer. It will
 779 not come from the general "terminate process" methods that everyone
 780 actually uses (and which can't be trapped). Killing an app 'politely' on
 781 Windows involves first sending a WM_CLOSE message, something that is
 782 caught already by the Qt frontend.
 783
 784 For more information see:
 785
 786 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
