What about just run those txns serially rather than attempting to do in

As soon as you see a MyISAM operation, have a thread that waits for all
replication up to that point to be committed, and then do the MyISAM
operation. (as there's no reason why other replication couldn't be
applied at the same time... after all, MyISAM isn't crash safe so would
never be consistent with InnoDB txns).
