To verify a transport we need a server factory, which is a callable

That Server is then used to construct transport instances and test

Currently this assumes that the Transport object is connected to the

current working directory. So that whatever is done

through the transport, should show up in the working

directory, and vice-versa. This is a bug, because its possible to have
505
URL schemes which provide access to something that may not be

result in storage on the local disk, i.e. due to file system limits, or
507
due to it being a database or some other non-filesystem tool.
