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

bzrlib.transport.Server.
654
That Server is then used to construct transport instances and test
655
the transport via loopback activity.
657
Currently this assumes that the Transport object is connected to the
658
current working directory. So that whatever is done
659
through the transport, should show up in the working
660
directory, and vice-versa. This is a bug, because its possible to have
661
URL schemes which provide access to something that may not be
662
result in storage on the local disk, i.e. due to file system limits, or
663
due to it being a database or some other non-filesystem tool.
