A store is like a parameter, except stores are independent of each
other, unlike parameters which are bundled together into a single
parameterization. This was observable in cases like the
example-action-after-suspension code checked in here, where dataflow
invoked a script, which parameterized current-dataflow-subject-id.
This captured *too much* of things like the pending-patch and
pending-actions. Subsequent `schedule-action!` calls' effects were
then lost.
