The patch as-written only clears the last-logged opid when we transition to 
TABLET_DATA_READY, which is only synced after tablet copy is successfully 
completed.

So the scenario summarized above wouldn't be affected negatively by this 
(correctness related) patch. I definitely agree we want to preserve the 
last-logged opid as much as possible (for availability reasons) and I am 
planning on ensuring that we do that in a follow-up patch.
