As noted in DM-9447, the following error was encountered when running coaddDriver.py on the COSMOS HSC-Y subset of the HSC RC dataset (DM-6816):

I am running the test now (the original command where I bumped into this). All looks good so far. I'll post again once it has run to completion.
Lauren MacArthur, did the test work?

Thanks, all! 
The code changes look fine to me, although I don't understand fully how pool works. I didn't run any test.
