This is very strange but I don't think it is releated. The CP winboard adapter
does not change priorities and the CP gui should be idle most of the time.
Maybe it has something to do with the way MFC handles sockets. An other thing
to watch for is proper configuration of the winboard adapter, it is very
flexible and therefor very easy to break.
