Measured again after the store fixes. Cutting the store primary's power no
longer hung requests, but leadership moved anyway: the lease had lapsed for
everyone while Patroni promoted the standby, and a standby asked first. The
new leader then spent about 25 s without its nodes, and so without its
judges.
A standby that saw the store out of reach now leaves the lease alone for one
renew round after the store returns. The default lease is 10 s, and a node
detects a control plane that died silently in 8 s (5 s idle, 3 s ping)
rather than 15.
