Thanks for making this. I think this is a bit too specific to mpi4py to be of broad use, especially with as little documentation as it currently has.

Do you have a suggestion on how to improve it?

especially with as little documentation as it currently has.

Do you mean the documentation specifically for debug_remote_on_single_rank or for the remote debugging feature in general?

Sorry, I did not mean to close this. I think it got auto-closed because the base branch went away.

I guess I could be talked into adding something like this, as long as it's

• included in the docs, and
• it has sensible semantics and is well-explained in terms of what it does. (what happens to the other ranks? they spin. what does the rank argument do? allow passing a communicator)
