…d 1s interval We need to avoid sending 15 requests in a row to locket and only waiting 1s each time in the event that the locket server is bogged down.

Very fast retries can cause a DoS in locket as existing requests pile up and must be processed 1-at-a-time before new requests are executed (due to SELECT FOR UPDATE holding the row lock)
Summary
My environment is slow enough where I occasionally see a locket request take longer than 1s. Components with a 1s retry will give up on the request because it take to long and then immediately make another request for ~15 retries. None of them succeed because they pile up on each other at the locket server.
