In hindsight, since Go 1.23, the only thing that was actually needed here was to remove the defer. In #18754 I've also avoided the extra timer allocations too. |

#18732 correctly identifies timer cleanup defers stacking unnecessarily. This handles the cleanup and channel management per Go 1.23.

FairMix.Nextcreated a new timer on each loop iteration and deferredtimer.Stop()until the function returned. When multiple iterations occurred (e.g., sources ended or Next waited on fromAny), timers accumulated unnecessarily and stayed alive longer than needed.Stop timers explicitly per-iteration inside
FairMix.Nextto avoid accumulating deferred timers and reduce redundant allocations.
