For the benefit of the list: I mis-remembered that osc=ucx was general
advice. The UCX docs just say you need to avoid the uct btl, which can
cause memory
Good question. I've filed https://github.com/open-mpi/ompi/issues/8379 so that
we can track this.

Why does 4.1 still not use the right defaults with UCX?
Without specifying osc=ucx, IMB-RMA crashes like 4.0.5. I haven't
checked what else it is UCX says you must set for openmpi to avoid
memory corruption, at least, but I guess that won't be right either.
Users surely shouldn't have to explore
