So runtime hangs should be solved both in 5.5 and 10.0. This leaves hangs during startup, which are unfortunate but not as critical as runtime hangs.
Are there any other known hangs?
If you are going to argue for deliberately keeping broken mutex_enter() / mutex_exit() in MariaDB, I will stay out of the discussion. I was only trying to get Buildbot green so that I can push my completely unrelated fixes for 10.0. Heh, not really. I just want to understand how much things are broken and how to fix them in 5.5 and 10.0. For 10.1 I already suggested MDEV-6654, which I belive is the right thing to do.
