http-429.sh is a helper for testing retry logic. It uses "test -f" to check for the existence of a state file and later uses "touch" or "rm -f" on that file to determine if it should return a 429. This method of managing state can fail if the helper script is invoked concurrently. However, this failure does not currently manifest itself since the helper is invoked sequentially. As a preventive measure, fix the state management logic so it relies on an atomic mkdir operation to mark that a 429 was returned. When $retry_after is "permanent", always return 429 now that we do not rely on a state file that is "touch"ed and "rm"ed to indicate when to respond with a 429.
