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