> Currently the view is updated while holding a lock, but reading the view id, members, or coordinator is done without a lock. This means when a thread sends a request and receives a {{SuspectException}}, it cannot simply wait for a new view before retrying: the initial request may have used the latest view, and only the members list could be outdated (even if read later).
> To allow atomically reading the view id and the member list, we should use an immutable structure similar to {{CacheTopology}}.
