Got this again now during normal operation. I don't think unity8 can do
anything here, it looks like the deadlock is somewhere between scopes
and zmq.

** Summary changed:

- unity8-dash hangs on startup
+ unity8-dash hangs in scopes backend

** Description changed:

- This is a forced crash, it was unity8-dash hanging on krillin rtm#10
- startup.
+ This is a forced crash, it was unity8-dash hanging. I got it twice on
+ startup, once during normal operation.
  
  Most suspect are threads 12 to 22.
  
  A `restart unity8-dash` it works again, so this is a race of some kind.
