I am no longer on chromium and has not been for years (I was actually only on V8), this git blame was due to a revert when I was sherrif.
I have no idea how to delete these - assigning over to dcheng@ who seems to have worked on this file, cc cmumford@ who also seems to have worked on it - hope that is ok

ricow@ thank you for looking at it.

CC +kalman who added the comment "TODO(kalman): These hisograms are both silly and untracked. Fix." Since we've managed to live without them for 3 years, I'd like to venture the possibility that we never needed them to begin with.

ricea@: kalman@ is no longer on Chrome either.  Punting to rdevlin.cronin who might know what to do with this.

"What to do" is simple: remove the histograms. They've been there for 3.5 years, and kalman@ noted 3 years ago that they were untracked. If we've managed to go this long without anyone caring enough about the data to add the histograms to histograms.xml, we can be extremely confident that no-one ever will.

The only questions remaining are who is going to write the CL and who is going to approve it.

@4 I'm not sure it's quite so cut-and-dried in all cases, but in this one, it probably is.  I'm happy to handle the CL.

mpearson@, in the past, you've requested that histograms like this that we're removing be added to histograms.xml with the <obsolete> tag.  Is that your preference here as well?

That's my preference but it's not required.  It's mostly a judgment call about how willing the code submitter is to do add the entry, how valuable it would be to glance at the old data, whether the old histogram made any sense (i.e., can a description be written for it?), and whether the name seems common enough that it might be inadvertently reused in the future.

Not sure why bugdroid didn't mention it, but revision a5dd79dcca3750d85310fb5cbf2b22f56b6f754b fixes this.
