Gittrac #4209/#4248:  All tests now pass; still need to do lots of
cleaning up, and checking to make sure I haven't introduced any
new errors...  (Made some changes to the abort tests to make them
more deterministic -- but we should add an abort test that makes sure
an abort removes other running jobs.)
Gittrac #4209/#4248:  Added new job_dagman_cycle-A test (passes,
but not yet enabled); added checking of node status file to
job_dagman_final-I (fails, dammit!).
