AutoUpdatingVar
A variable that updates itself. latest can be called from multiple threads, which are all guaranteed to get the latest var.
An AutoUpdatingVar attempts to get the variable immediately upon class instantiation. If this fails, there are no further attempts (unless specified via handleInitializationError1), and the effect returned by thereadymethod will complete unsuccesfully. If it succeeds, the effect completes successfully andlatest` can be safely called.
Failed updates other than the first (those that throw an exception) may be retried with various configurations.
A successful update schedules the next update, with an interval that can vary based on the just-updated var.
