@jjhursey could you add commit b643852 to this PR?

[jjhursey]

It didn't apply cleanly, so I'll have to investigate a bit. I'll try to get it done today.

Outside the errors in the CI things looks good. I confirm that the original patch works in master.

@bosilca I tested the current v3.1.x HEAD without this patch and it seems to be working correctly.

Can you double check the commands below that I am trying to reproduce the same problem you are encountering.

I confirm this is not necessary on the current 3.1. Thanks @jjhursey for investigating.

[jjhursey]

Ok. I'll close this PR then, and the one for v3.0.x. Thank for the confirmation.
