We already run the code paths that were breaking 8 or more times.
Hundreds of times in fact for some :(.
The odds of a broken path triggering after it gets through, assuming
each time we exercise it is equally likely to show it, are roughly
3/times-exercised-in-landing. E.g. if we run a code path 300 times and
it doesn't show up, then it's quite possible that it has a 1%
