+ Priority coefficient decays all the job priorities such that they slowly
+ drift towards the front of the run queue. This coefficient defines a
maximum
+ time window over which this algorithm would operate. For example, if
this
+ value is too small (0.1), after a few cycles quite a few jobs would end
up at
+ priority 0, and would render this algorithm useless. The default value
of
+ 0.98 is picked such that if a job ran for one scheduler cycle, then
didn't
+ get to run for 7 hours, it would still have priority > 0. 7 hours was
picked
+ as it was close enough to 8 hours which is the default maximum error
backoff

Good eye! Thanks. Pushed the fix
