pub const REQUEST_TTL_SECS: u64 = _; // 2_592_000u64Expand description
How long an unanswered access request survives (D72).
Long, because the person who asked cannot be reminded and an operator who is away for three weeks should not come back to an empty queue. Finite, because an unanswered request is a row in a file that nobody is ever going to answer, and the alternative to a sweep is an operator deleting rows by hand.
