Regression range:
https://chromium.googlesource.com/chromium/src/+log/61.0.3149.0..61.0.3150.0?pretty=fuller&n=10000

One change in this range that seems suspicious is:

Watk@, can you take a look and make sure there aren't edge cases where memory isn't being freed or where a huge number of allocations could be cached?

Actually that change is to code that is not currently shipping anywhere.

I seem to repro a massive GPU memory leak on linux on a build at 61.0.3150.0 (just open a bunch of tabs and cycle through them), but not top-of-trunk. I will bisect the regression and (if confirmed) the progression, but this might end up as a wontfix.

Well, this is a dup of  crbug.com/740121 , with the regression at https://chromium-review.googlesource.com/c/558472/ (in the range) and the fix https://chromium-review.googlesource.com/c/566332/

IOW the system works.
