This is taking more time than I expected since I'm running into some other issues with my test case. I think I have it but am going to wait for a review.

Should be fixed in bc863c3207c216fb245fda06cd6bf19c6940ad0e. Instead of maintaing a count of stale replies, it switches the request to go to the auth mds, and if it already was it looks to see if the auth mds might have changed by comparing the previous mds' caps to the current auth caps on the inode, then (if they've changed) sends back. Otherwise, or if there is no inode, it just returns the ESTALE.
Since this is timing-dependent it's hard to test but I haven't seen ESTALE in repeated tests that were pretty good at returning them to me.
