I'm not disputing the general value of the backoff, nor about the value of an
initial value of 60 seconds. In terms of avoiding congestive collapse one does
indeed want the exponential backoff. I'm just in agreement with the person from
Hitachi that allowing someone to tweak the backoff has a certain value.
60 seconds is already a trade-off between a pure (non capped) exponential
backoff and capping the value.
