Yes, the first 3 stages of this workflow worked just fine -- I have some 
results transferred back to my submit host (from the original run, not the 
restart). None of the results from stage 4 were transferred back (both from 
the original run and the restart run). Stage 4 has about 3500 jobs and this 
is when the queue got saturated. Stages 1-3 never had more then 50 jobs at 
the same time... The workflow is still going...
