Hello!

Thank you for looking into this

> If your working-set size does hit swap, then you are in for a terrible time. For the borderline case, https://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=shrinker should hopefully help.

In this round of testing (with "shrinker" kernel and upstream 4.13rc6) I
noticed that now animation playback is struggle few times before it completely
stuck (earlier it always happened on first playback). Unfortunately I didn't
find noticeable difference between "shrinker" kernel and upstream 4.13rc6.

Later, while I tested 4.13rc7, I also find that if I switch to another tab in
the beginning of playback, and give system enough time to push data from RAM to
swap, then I can switch back, let browser playback animation, and does not get
freeze anymore - does it give hint where root cause can be?
