 629 Signals and Windows
 630 ===================
 631 The SIGHUP signal does not exist on Windows and does not need to be handled.
 632
 633 Windows handles SIGFPE and SIGSEGV signals as expected.
 634
 635 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 636 cause a new thread to be spawned. This may well result in unexpected
 637 behaviour by the single-threaded LyX.
 638
 639 SIGTERM signals will come only from another process actually sending
 640 that signal using 'raise' in Windows' POSIX compatability layer. It will
 641 not come from the general "terminate process" methods that everyone
 642 actually uses (and which can't be trapped). Killing an app 'politely' on
 643 Windows involves first sending a WM_CLOSE message, something that is
 644 caught already by the Qt frontend.
 645
 646 For more information see:
 647
 648 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
 649 ...signals are mostly useless on Windows for a variety of reasons that are
 650 Windows specific...
