Ok, so youtube (unlike facebook), I can test in firefox. Although it's
70, not 71 or nightly. And it doesn't seem to fail for me.

Of course, maybe the reason it doesn't fail for me is that I have a
patch in my tree that may be the fix. It's a very small race in
select()/poll(), and it's small enough that I wonder if it's really
the fix for this, but hey, it might be.

It also might be that your version of firefox is different, or just
that you're hitting something else that I'm just not hitting.

But I committed my patch and pushed it out, so that you could see if
that fixes it for you.
