I realized that, even in the current system, such reads can't really do any harm. Because they are not part of a task, they will occur no matter what (only tasks can be skipped). If you leak the data you read into a task, that is bad, but that is equally bad if you are in a task. *Writes* to tracked state, on the other hand, should never occur except from within a task (and the task then records what things you read to compute it). Once we complete the shift to on-demand, these properties will hold by construction (because the on-demand struct enforces stateless tasks where leaks are impossible -- except by having shared mutable state in the tcx).
