 725 Signals and Windows
 726 ===================
 727 The SIGHUP signal does not exist on Windows and does not need to be handled.
 728
 729 Windows handles SIGFPE and SIGSEGV signals as expected.
 730
 731 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 732 cause a new thread to be spawned. This may well result in unexpected
 733 behaviour by the single-threaded LyX.
 734
 735 SIGTERM signals will come only from another process actually sending
 736 that signal using 'raise' in Windows' POSIX compatability layer. It will
 737 not come from the general "terminate process" methods that everyone
 738 actually uses (and which can't be trapped). Killing an app 'politely' on
 739 Windows involves first sending a WM_CLOSE message, something that is
 740 caught already by the Qt frontend.
 741
 742 For more information see:
 743
 744 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
