 616 Signals and Windows
 617 ===================
 618 The SIGHUP signal does not exist on Windows and does not need to be handled.
 619
 620 Windows handles SIGFPE and SIGSEGV signals as expected.
 621
 622 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 623 cause a new thread to be spawned. This may well result in unexpected
 624 behaviour by the single-threaded LyX.
 625
 626 SIGTERM signals will come only from another process actually sending
 627 that signal using 'raise' in Windows' POSIX compatability layer. It will
 628 not come from the general "terminate process" methods that everyone
 629 actually uses (and which can't be trapped). Killing an app 'politely' on
 630 Windows involves first sending a WM_CLOSE message, something that is
 631 caught already by the Qt frontend.
 632
 633 For more information see:
 634
 635 http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
 636 ...signals are mostly useless on Windows for a variety of reasons that are
 637 Windows specific...
