 632 Signals and Windows
 633 ===================
 634 The SIGHUP signal does not exist on Windows and does not need to be handled.
 635
 636 Windows handles SIGFPE and SIGSEGV signals as expected.
 637
 638 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 639 cause a new thread to be spawned. This may well result in unexpected
 640 behaviour by the single-threaded LyX.
 641
 642 SIGTERM signals will come only from another process actually sending
 643 that signal using 'raise' in Windows' POSIX compatability layer. It will
 644 not come from the general "terminate process" methods that everyone
 645 actually uses (and which can't be trapped). Killing an app 'politely' on
 646 Windows involves first sending a WM_CLOSE message, something that is
 647 caught already by the Qt frontend.
 648
 649 For more information see:
 650
 651 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
 652 ...signals are mostly useless on Windows for a variety of reasons that are
 653 Windows specific...
