Mysterious logging errors with sftp access to live data.

sftp-root and sftp-repo run on xander: mysterious logging errors

• happened with repo on localfs, live data on sftp (sftp2)
• running with both on localfs (sftp3): worked fine
• so there's something wrong, possibly in paramiko
• tried a script to transfer 140 gigs of data with paramiko, but this failed, the transfer speed is very slow (less than 1 MiB/s)

Removing 1.0 blocker tag: access to live data over sftp is limited enough that it's not something I want to guarantee for 1.0. Fixing the limitations may require patching paramiko or replacing it with another sftp implementation. --liw

I can't reproduce this with the current version of paramiko on Debian wheezy (1.7.7.1-3.1) and the current obnam (1.3). done --liw
