Connection lifetime: Each player or group-member connection resolved by this function is retained through the native call. A disconnect or reconnect during a callback cannot destroy that retained connection or switch the ongoing call to a replacement. A later Lua call resolves the current connection. This does not extend the lifetime of unrelated spawn or item userdata.
