I will often run pipelines with qsub even though the pipeline is running with the "SGE" plugin. This allows me to set run_without_submitting on nodes that take very little processing without worrying about using too much resources on the cluster head node.
After upgrading to 0.10 I found that the pipelines will hang after submitting the jobs for the first MapNode in the pipeline, never noticing that the jobs did in fact complete (and thus never kicking off the next set of jobs). The output files for the MapNode jobs are created in the working directory.
