[ExM Users] Return worker result to swift script

[Scott Krieder]

Hi Justin,

This makes sense, however I hope I don't have a design flaw in my
implementation. Right now, I never actually call that tcl fragment. Instead
I read that fragment name and implement the logic in the worker.

Would you be around Argonne tomorrow? Maybe I could stop by in the morning?

Thanks,
Scott
