Yep. It should help shrink the audit container ID patchset and
perhaps more importantly it should put some distance between the
connected-record debate and the audit container ID debate.
I understand we are going to need a "local" context for some things,
the network packets are probably the best example, but whenever
possible I would like to connect these records back to a task's
context.
