*The PEAR support version of this just forwards calls relating to external resources and cas pools to the parent.* My understanding is that the RM's used by pears are created by copying the 5 resource maps and the CasManager --- so deleting one pear's RM would delete the resources shared by the others.
We also have a use case where multiple pipelines need to share resources but can't share the CasManager as their typesystems are different, and may be created much later. We can use the 5-arg constructor to create a subclassed RMs that share the resources, but this doesn't share the resources loaded by the original pipeline.
