There were specific bugs with bzr-0.8.2 and paramiko > 1.5.5. bzr's
readv() would mess up because it requested a prefetch() of the whole
file, but then would request just specific chunks, and request them out
of order. Paramiko 1.6.2+ supports that, and bzr-0.9 doesn't do it any
more. So we have a little bit of both sides fixing the problem :)
