[Csync2] 3-node masters and root-owned files

[Kevin Cackler]

Funnily enough, we are also experiencing this issue with the root owned 
files. Randomly, and without any definable pattern, so far as we can 
tell, we'll get a file that suddenly is owned by root:root with rw 
permissions and we have to go in and correct the permissions. So far we 
haven't been able to nail down the cause of this.
