> When {{ClientCache.stopClient()}} is called to stop the IPC client, if the client
> is blocked spinning due to a connectivity problem, it does not exit until the policy has timed out -so the stopClient() operation can hang for an extended period of time.
> This can surface in the shutdown hook of FileSystem.cache.closeAll()
