The spoolss tests are testing the (very odd) rpc call-back
functionality that requires the spoolss server to make a reverse call
to the client to deliver the notifications.  The ntvfs file server
helps provide one of the layers involved, to allow the smbtorture
process to listen as an smb server and then provide a specail RPC
interface.

As we don't otherwise implement the client side of this protocol, the
means used to implement it are not important, we are testing the server
against a instrumented mock implementation.

This isn't the only reason that part of the codebase is used, but I
hope I can clarify at least this one for you.

Thanks,

Andrew Bartlett
