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