The solution is obviously to have a leap second every half year, even when the difference with solar time is too small. Just alternative positive and negative leap seconds, and for additional fun, don't have a leap second when the difference with solar has shifted (in the right direction; it should be possible to keep the difference less than 1.5 second, probably much less). We could even do this every month, just to make sure there's enough testing opportunity.
