to use on the operation's timeout value as the maximum wait time. Do not use the same value as the operation's timeout, since this introduces a race condition.

An operation becomes acknowledged when the first response is received.

NOTE: Some operations never receive any responses, so they are never acknowledged. Examples: beginProvide, beginInterest, and beginQuery.
