As seen intermittently during CV, test "ConsistentStateAfterShutdown/Clean" fails with seqno mismatches:

Note: Google Test filter = CleanOrUnclean/PersistToTest.*

Anecdotally I believe I've seen this most on cv-mad-hatter-windows-03, which has a note in it's description that its IO is slow; so perhaps we arn't correctly waiting for something here?
