[Seaside] "remove" command

After hours of playing around with "self halt" I finally found
a solution for my problem.
The problem is the call to "SeasidePlatformSupport vmStatisticsReportString"
in WADispatcherEditor>>renderContentOn:. When i unregister the session I close
the connection to the naming service (RequestBroker). Unfortunately the
vmStatisticsReportString method still tries to access data that was published
in the naming service.
The only solution I found, was to remove the line from the renderContentOn
method.

I'm still new to smalltalk, so I don't know if this solution is any good.
It seems to work but maybe I missed something.

WARegistry>>clearHandlers
     self mutex critical:
         ["Unregister all sessions"
         handlersByKey notNil
             ifTrue:
                 [handlersByKey associationsDo: [:assoc | [assoc value unregistered] fork]].

	"Remove all handlers"
         handlersByKey := Dictionary new.
         keysByHandler := Dictionary new]

WADispatcherEditor>>remove: anEntryPoint
     dispatcher removeEntryPoint: anEntryPoint.
     anEntryPoint clearHandlers.

WADispatcherEditor>>reset: anEntryPoint
     anEntryPoint clearHandlers.
