Hi Chao, do I understand it correctly that the problem is that the second thread is not moved after installation of the update and system reboot? Are you able to reproduce this reliably? I'm not able to reproduce it at all, but I think I know what's going on, and I believe the updated patch from bug #1593299 should solve it. I'll do a new build and a respin ASAP.
