Context
We have a custom event source with a long polling interval (5 minutes). This plays havoc with the Event Sourcery graceful shutdown mechanism as it will take up to 5 minutes to stop.
We set
@shutdown_requestedupon receivingSIGTERM. But we only check@shutdown_requestafter waking from the poll wait sleep.Change
Instruct the main thread to wake upon receiving
SIGTERMorSIGINT. So we don't wait the remainder of the poll wait sleep.
