> Once a TaskContext has been sent to a machine then the other tasks with the same context can use the fetched TaskContext. The same container can re-use the TaskContext cached in memory from a previous run of the same task. A hash/checksum of the TaskContext could be used to identify identical task contexts that do not need to be fetched.
