AlmosAll uses of NewDeadlineWorker, which relied on secondary values, were used in a racy fashion,
which could lead to inconsistent errors/data being returned. It also propagates the deadline downstream.
Rewrite all these to use a generic WithDeadline caller that can return an error alongside a value.
Remove the stateful aspect of DeadlineWorker - it was racy if used - but it wasn't AFAICT.
Fixes races like:
