> During defrag a collection of candidate "rich" users and "rich" jobs is made, which forms
a collection of candidate shares to evict to make space for NEEDY jobs.  There is a case where
a "rich" job may be very rich and yet allocated entirely on machines unsuitable for any NEEDY
job.  The bug to fix, is to properly identify this situation and remove the unsuitable shares
from consideration.
