If the file is locally unchanged, then why would the client even try to 
sync the file again?
Is it because it is re-trying the operation causing an error before 
(i.e. the rename in this case)?

If so, then wouldn't a fix for this be as "simple" as checking for such 
a failed operation,
before retrying it, whether it has already been done successfully in 
the meantime?

Randolph
