[~navis] I have added a comment on reviewboard on the latest update there. 
But there seems to be slight difference in the HIVE-5901.6.patch.txt patch here and latest one in reviewboard. In HIVE-5901.6.patch.txt the 'boolean shutdown' has been made volatile, which is not necessary as you pointed out with the changes to make the functions synchronized.
