If you shutdown Zope by pressing CTRL+C / Break repeatedly, an AttributeError is raised in Signals.WinSignalHandler.py, line 191 in method "consoleCtrlHandler" or method "signalHandler", line 245.

This happens if the method "shutdown" has been called before, because it sets "self.registry" to None which can't be used afterwards.

Attached is a cvs diff against the current CVS branch "Zope-2_7-branch" that fixes these two issues.
