To verify a transport we need a server factory, which is a callable
402
that accepts no parameters and returns an implementation of

bzrlib.transport.Server.
405
That Server is then used to construct transport instances and test
406
the transport via loopback activity.
408
Currently this assumes that the Transport object is connected to the
409
current working directory. So that whatever is done
410
through the transport, should show up in the working
411
directory, and vice-versa. This is a bug, because its possible to have
412
URL schemes which provide access to something that may not be
413
result in storage on the local disk, i.e. due to file system limits, or
414
due to it being a database or some other non-filesystem tool.

This also tests to make sure that the functions work with both
417
generators and lists (assuming iter(list) is effectively a generator)
