> While working on branch-2, I ran into an issue where a retryable error kept occurring and code in AsyncRequestFutureImpl would reduce the backoff wait to 0 and extremely rapidly eat up a of thread stack space with recursive retry calls. This little patch stops the backoff wait kill after 3 retries. Chosen kind of arbitrarily, perhaps 5 is the right number, but I find large retry counts tend to hide things and that has made me default to fairly conservative in all my arbitrary number picking.
