When running in serial mode, CODES checkpoint test is failing to find associated model-net LP and gives a fatal error of sending to invalid MPI rank. IIRC the test used to run fine until we made the modelnet_dragonfly_router changes to the mapping API. To reproduce the error:

./tests/test-checkpoint --sync=1 --codes-config=../tests/conf/test-checkpoint-dfly.conf

This issue is blocking me right now so I am labeling it as high priority.
