      Description

      There is a race of tagging and closing connections when stepping down. After the connection is established but before it gets tagged, there's a small window where the connection may be closed on stepdown.

      We could fix this by having internal connections tagged in other ways than _isMaster for every incoming connections (maybe logical session?), or only hanging up connections that have locked the database / issued any commands, or not hanging up connections at all but instead just returning a stepdown error.
