----------------------------------------
I added a DummyOperator at the beggining of each subgraph and now it got even stranger, it will execute only one of the subgraphs and then hang

> I'm trying to have some subdags execute one task at a time. The way I found was to create a first pool for the SubdagOperators (pool1 in the attached code file) and a second one for the internal tasks (pool2). However, it appears that pools for subdag elements are not being respected. Running airflow 1.9.0.
