[mpiwg-sessions] [EXTERNAL] Sessions/Spawn

[Wesley Bland]

If that’s the solution, that’s fine. The other option is to hold MPI 4.0 if this is a showstopper. I’m not that familiar with the problem so I was trying to figure out which side this is on.

Thanks,
Wes

So, the idea to put a stop-gap measure in that for now disallows certain parts, and that could be done as an errata. Hence, it would be nice to get this cleaned and ready, but I don't think we have a huge rush here.
