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.
