[slurm-users] Create users

[Paul Edmon]

This is true.  I've seen this happen before in our set up if sacctmgr 
happens to wedge.  It doesn't happen very frequently though and doesn't 
impact us that much.  We've been running in this fashion for years now 
with only very infrequent degradation. We do about 80,000 jobs per day.  
Plus we only add them if they don't already exist so the impact is only 
when new users appear.
