Night of the Living ROOT

This is the awesome error ROOT gave me today:

Error in : Cannot open file: recHits/hRHSumQ22_Summary, TGraph is Zombie

Appearently the "child" and "parent" processes lost connection, and the child is left running when the parent leaves. There is no one to clean up after the child. I thought this should probably be called an "Orphan process" instead of a "Zombie process" but an Orphan is a process that is adopted by another process and cleans up after it, maybe I should call this clean-up process the "Grandparent"?
