This change is a partial fix for the problem of long cluster failovers. This change addresses part of that problem: long newbie-broker catchup times.
At this time, it looks as though there are two distinct mechanisms causing these long catchup times. They roughly divide into a population of times less than 20 seconds, and a population of much longer times (up to hundreds of seconds).
This fix addresses only the shorter times. In a test of 25 failovers before and after the change, it reduced those times by an average of nearly 50%. A T-test on the times indicates that the likelihood of the observed change happening randomly is less than 2%.
