Only when you forget to do it.

We recently had a problem when a broken dataset ended up getting 
deployed. It was controlled by a top-level dag with subdags. After 
grubbing through various condor log files, it turns out it was due to 
one of the inner dags failing, but the top level DAG had POST scripts to 
notify progress, and they weren't handling $RETURN properly.

So I was just wondering if it was possible to idiot-proof this.

Brian.
