What's supposed to be happening here is that we are streaming out from
the groupcompress level, which is going to write one long file in a
series of chunks. The base class implementation in transport.py and
AppendBasedFileStream changes them into a sequence of
transport.append_bytes calls. However, since some servers don't
support append, we need to make sure that by the time it gets to the
ftp level we just open the file once and write one long stream.

By the way for openftpd I think there is a configuration option to
allow appending. But patches to avoid needing to set it would still
be great.
