I suppose we should save the last entryID that was indexed at shutdown time, 
so that the indexer task can resume at the next startup. We'd also need some 
coordination with slapindex, so that if you ran slapindex after shutdown, it 
would erase the saved status. Rather than add any fields to the DB index 
files, it would probably be OK to write the status in the cn=config tree.
