The common cause of sync_combine_commit() will be unexpunge on the master.

I imagine that a single GUID appearing in cyrus.index and cyrus.expunge is 
bad news. sync_server needs to know about the expunge index. It did in my 
original code base, but replication got merged before delayed expunge.

More later. In theory I'm on holiday this week.
