[Ncep.list.nems.announce] Planned commit to NEMS trunk for ticket #41 NUOPC/OCN integration

Hi again,

I would like to commit a change set that has one very small modification 
in one file, "job/regression_tests/rt_gfs.sh", compared to the sandbox I 
referenced earlier. The new sandbox (again with regression results from 
Zeus) can be found on Zeus:

The only difference compared to the earlier announced sandbox is in the 
one file "job/regression_tests/rt_gfs.sh", dealing with the way the 
script is figuring when a job has completed under PBS. The new version 
of this file uses qstat for PBS, as did the earlier proposed change, 
however, it does it in a smarter way which doesn't result in waiting 
several minutes after a job has completed before continuing with the 
validation step. There are no other changes, in any other files, 
compared to the earlier announced change set, and both sandboxes are 
available for inspection and have completed regression testing.

Please let me know if there is any objection to commit from the more 
recent sandbox. I am planning to commit tomorrow around 9amET.
