Sorry for the late reply.  I was in a bicycle-vs-car accident a  
little over a week ago and am still catching up on email.  Details  
for the curious here:

Could you email me a copy of your paramiko.log for clues?  (Feel free  
to strip out any passwords or sensitive info.)  I can try to debug  
this off-list.

Newer SFTP protocol versions support file locking, and I've been  
meaning to try adding support for some of those new things (in the  
hopes that SFTP servers will be implementing them soon).  But until  
then lockfiles should work. (Is that what tla/arch does? I never dug  
into the tla code enough to figure out what was going on there...)

I've been using paramiko to run a tla archive (hosting paramiko  
itself, naturally ;) so I have pretty good confidence in it, in general.
