Ah - yeah, that's right.  Except that the restart only got negotiated after
each folder was processed, and if you're pushing a new folder with 200,000
messages (say, after a user move in our case) then that got a bit memory
hungry and all sorts insane.

Does this mean there is no way to get single-instance-store on a replica
if you're rebuilding it from scratch?

(short of some script that post-adds it with uuid scanning magic...)
