I would accept this, and prefer it to "I have run something in the
background that I know will not create output but fails to close
stdin/stdout/stderr and now I can't log out cleanly".

That's what "all implementation I'm used to" do: if I logout the
connection is closed, no matter what background processes are still
alive.

The background processes will then get some kind of error (I assume
vhangup -> I/O error or something like this) if they try to write
something after the connection is already closed.
