I don't have any experience with the replication code, but I use almost 
the exact same procedure as you to restore mail for users.  The only 
difference is that I only restore the cyrus.header file and the ##. files. 
I never restore the cyrus.cache and cyrus.index files.

I can't remember the exact reason, but I think whenever I had those files 
around, I couldn't get reconstruct to work on the restored mailbox.  Note 
that this was on Cyrus 2.1.x originally, so maybe it works fine anyways in 
2.2.x and 2.3.x.

Something worth trying anyways.
