For Go 1.24, it now defaults to multipathtcp="2", thus
enabled by default on listerners. Using multipathtcp="0" reverts to the
pre-Go 1.24 behavior.

### Go 1.23

Go 1.23 changed the channels created by package time to be unbuffered
(synchronous), which makes correct use of the [`Timer.Stop`](/pkg/time/#Timer.Stop)
and [`Timer.Reset`](/pkg/time/#Timer.Reset) method results much easier.
