> In the call path of {{Docker::inspect()}}, each continuation currently checks if {{promise->future().hasDiscard()}}, where the {{promise}} is associated with the output of the {{docker inspect}} call. However, if the call to {{docker inspect}} becomes hung indefinitely, then continuations are never invoked, and a subsequent discard of the returned {{Future}} will have no effect. We should add proper {{onDiscard}} handling to that {{Future}} so that appropriate cleanup is performed in such cases.
