      Description

      The parallel replication feature (MDEV-4506) has some potentially long-running
      waits, when a transaction in one worker thread waits for another to commit.

      These waits are currently not killable. This is especially a problem if the
      waits end up deadlocked on one another, which can happen if the parallel
      replication feature is used incorrectly.

      All relevant waits need to be implemented in a way that allows them to be
      killed. And in case of kill, the code needs to handle the error and correctly
      roll back the killed transaction and so on.
