When there is a link failure while an ongoing MEET request is sent the
sending node stops sending anymore MEET and starts sending PINGs. Since
every node responds to PINGs from unknown nodes with a PONG, the
receiving node never adds the sending node. But the sending node adds
the receiving node when it sees a PONG. This can lead to asymmetry in
cluster membership. This changes makes the sender keep sending MEET
until it sees a PONG, avoiding the asymmetry.
