How do you support MPI dynamic processes over MXM?

I answered to the PR but I'll bring my comment here as well. In addition to
the performance implication, there might be a correctness implication here.
del_procs does not have to be called globally by all participating
processes in same time, and can be called with a subset of processes. As an
exam
Mxm needs that barrier. Otherwise some ranks may hung trying to close mxm
connections

It’s your code, so you are welcome to do this if you want. I’ll just point out
that his is a really big hit in total execution time at scale as it will be
done in addition to the barrier already performed in MPI_Finalize
So you are going to do _two_ barriers during shutdown.
