It looks like range contains my CL and revert of my CL at the same time, bisect looks wrong to me. I restarted pinpoint job.

Both CLs from above fail to build for some reason. There's also 

[heap] Remove custom Scavenger trace events
By mlippautz@chromium.org

in-between.

My CL is just removing two trace events that are not used in a single metric. This should be a complete noop.

Then this must be a benching artifact, assuming that land+revert of kozy's CL is also a noop.

Yeah.. Other bots don't show this regression at all. Closing.
