sync_entry->data_size(i) still works at this point. But you're out of luck on
the entry that has now gone. We spoke earlier today about how we will actually
have to refcount the SimpleEntryImpl; perhaps a TODO(felipeg,gavinp): Once
SimpleEntryImpl is ref counted, update the index correctly in this case.

Done.

Maybe add SimpleSynchronousEntry::GetFileSize()?
