Comment:

 (In [3359]) Fix the broken logic in the random directors picking routine.

 Drop the consistency check for health-changes, at the cost of a
 slight bias[1] for hosts before, or after, then one that changed health,
 according to how its health changed.

 Count all failures to pick against the retry count.

 Fixes #361
