It passed on the next build attempt. I don't think this is a real issue. Maybe 
the arm buildbot is just not provisioned very well.

The timeout appears to be 30, per the failing test logs. I don't know if 
raising further it is the right call, because this seems to happen so rarely, 
and you probably want to keep the value low so you can iterate on tests faster.
