Review comment:
This is fragile--we should not be (attempting to) interpret values as dicts
of windowed value parameters and creating globally windowed values if anything
goes wrong. Instead, store the WindowedValue object in tv.value.
(Alternatively, one could let `events` be full WindowedValues rather than
TimestampedValues, but that might be a bigger change.)
