[kepler-dev] Workflows non-terminating in nightly build

Maybe you should use the test actors to test for valid results rather 
than just running a larger workflow like PIW.  There's really no way to 
tell what went wrong if PIW etc. fails in its current configuration. 
Using the test actors generates specific exceptions when the test fails 
and so it lets you pinpoint the critical stuff and test if the right 
values are being produced for known inputs. I think that would probably 
fix many of these issues.
