 772 Signals and Windows
 773 ===================
 774 The SIGHUP signal does not exist on Windows and does not need to be handled.
 775
 776 Windows handles SIGFPE and SIGSEGV signals as expected.
 777
 778 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 779 cause a new thread to be spawned. This may well result in unexpected
 780 behaviour by the single-threaded LyX.
 781
 782 SIGTERM signals will come only from another process actually sending
 783 that signal using 'raise' in Windows' POSIX compatability layer. It will
 784 not come from the general "terminate process" methods that everyone
 785 actually uses (and which can't be trapped). Killing an app 'politely' on
 786 Windows involves first sending a WM_CLOSE message, something that is
 787 caught already by the Qt frontend.
 788

 790
 791 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
