Public bug reported:

Several people now, including Brian Haley and me, have been chasing down
this stack trace [1] for a few weeks.  We've seen it in failed jobs and
we begin chasing it down only to find out that it is a red herring.

I'm filing this bug because we ought to capture what we know about it,
figure out if it is correlated with any failures, and hopefully
eliminate the trace so that no longer distracts us from other problems.

I was poking through the stack trace in github.  Since I had the links
handy, I thought I'd include them here [2-11].  Also, this logstash
query might be helpful [12].
