Hang on a minute. Volker tested the connected-but-not-active
resources of smbd at around 200k I think. With the waf build
producing smaller binaries I don't see any reason to keep
the ntvfs/ code in there at all.
Having a second file server embedded - used only in certain
cases and having differing semantics is a receipe for disaster,
and not a good idea for long term stability of this release.
That's a big sticking point for me. I though we'd decided
s4 fileserver was smbd code - end of story. The details
were how to do the integration.
Now I hear the ntvfs/ server is coming back from the dead.
I didn't sign on for that at all.
