Fix for a probe test that failed every once in a while due to the early-majority change previously committed. Sometimes a write would return success before the third node had succeeded and the probe test would look for on-disk evidence and fail, when it would've been fine had it waited just a bit longer for the third node to complete. Since there's no real way for the probe test to know when all three nodes are done, I just made it retry once a second for several seconds before reporting an error. There may be more tests like this we'll have to fix as we run across them. Change-Id: I749e43d4580a7c726a9a8648f71bafefa70a05f5
