A kludge to fix a kludge. *SMBSERVER forces a one server-service per
node model, which is completely unneccessary.

Do you? I'm probably missing something...
Where in the process could leakage occur? The port 138 datagram packets
don't use *SMBSERVER (do they?!). How is the Server Service used?

It's a different system, probably written by a completely different set
of people.
