Looks like the failure in basic-store-each has been happening since at 
least 2016-07-10, but only on one specific BDW machine 
(ro-bdw-i7-5600u). Failure is:

Intermittent, though, as Chris's recent results show:

making it very difficult to determine whether it's a real regression or 
some problem with that specific machine -- it doesn't happen on the 
other BDWs, but they're all slightly different.
