 Issue 602325  has been merged into this issue.
One graph recovered, one didn't. Trying another bisect on the one that didn't.
Bisect job timed out after 24 hrs, but we get partial results.

rschoen@: There is a huge improvement in the graph at Chromium Commit Position range: 387324 - 387345, not sure if we still need bisect on this?

I think we can close this, the improvements seem to have stuck.
