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