Normally this shouldn't happen, but it could be used as an attack vector when somebody creates this scenario manually and links to it, so pods start fetching the loop.
When two threads fetch the same entity (which can happen when receiving the same entity twice), this isn't a problem, because the receive method can handle duplicates anyway.
