Review Comment:
```suggestion
for attempt in run_with_db_retries():
with attempt:
tis = session.query(TaskInstance).filter(
TaskInstance.trigger_id == trigger_id,
TaskInstance.state == State.DEFERRED
)
for task_instance in tis:
# Add the event's payload into the kwargs for the task
next_kwargs = task_instance.next_kwargs or {}
next_kwargs["event"] = event.payload
task_instance.next_kwargs = next_kwargs
# Remove ourselves as its trigger
task_instance.trigger_id = None
# Finally, mark it as scheduled so it gets re-queued
task_instance.state = State.SCHEDULED
```
i think separating the retry logic from the actual work makes things a
little more digestable
