"which may be spurious" - Can you give examples on this please as per RL discussion. Namely that things like restarting servers / load balancers / etc will knife any ongoing connection, and we want to effectively ignore that case.

// connection error warnings we simply retry the /sync immediately. Only
// if *that* one fails too do we say the connection has been lost.
// Should we emit a state like "MAYBE_CONNETION_LOST"?
