 622 Signals and Windows
 623 ===================
 624 The SIGHUP signal does not exist on Windows and does not need to be handled.
 625
 626 Windows handles SIGFPE and SIGSEGV signals as expected.
 627
 628 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 629 cause a new thread to be spawned. This may well result in unexpected
 630 behaviour by the single-threaded LyX.
 631
 632 SIGTERM signals will come only from another process actually sending
 633 that signal using 'raise' in Windows' POSIX compatability layer. It will
 634 not come from the general "terminate process" methods that everyone
 635 actually uses (and which can't be trapped). Killing an app 'politely' on
 636 Windows involves first sending a WM_CLOSE message, something that is
 637 caught already by the Qt frontend.
 638
 639 For more information see:
 640
 641 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
 642 ...signals are mostly useless on Windows for a variety of reasons that are
 643 Windows specific...
