      Description

      **Reported in Launchpad by Seppo Jaakola last update 22-11-2013 06:59:07

      High priority threads (slave threads, replaying threads, total order isolation threads) are not protected from kill signal and attempt to kill high priority thread can cause server to hang. One such a scenario is reported in MariaDB project: https://mariadb.atlassian.net/browse/MDEV-3924

      As a fix, high priority threads should be protected from kill.
