I've been taking a look at this 
(https://github.com/stackforge/swift-ceph-backend and forks etc). Looks 

I have some possibly dumb questions :-)

1/ Async updates

There's a comment in rados_server.py about not handling these. What 
exactly is the issue? (I note in Juno we need to add a policy arg, but 
they seem to work AFAICS).

2/ Replication

Doing some testing to 2 regions and 2 zones (each region with its own 
ceph cluster), I can get the ceph data out of sync between the regions 
if I stop one region and make changes in the other (then restart). This 
same test works fine for standard swift object backend. Are we in need 
of some more code in the replication side of things?
