pub const LEASE_TTL: Duration;Expand description
How long a lease stays believable after its last beat.
Longer than [WAIT_SLICE]’s hand-back gap by a wide margin: a slice that
ends with Wait::Pending leaves the asking agent a moment to call
magi ask --wait again, and a reply leaves it a moment to call --thread.
A holder that beats every [POLL] and is silent for ninety seconds is gone
or about to be, and a lease that is merely between two calls must not be
mistaken for that - the daemon waiter would start a second agent on a
conversation the first is still in.
