Resolution: --- → FIXED
Target Milestone: --- → 88 Branch

Is this worth uplifting to 87?

Flags: needinfo?(mgaudet)

I suspect yes; I'd like this to bake on nightly a bit longer. I'll submit the uplift request on Wednesday if that sounds OK?

Flags: needinfo?(mgaudet)

Just note that we build the last beta for 87 on Thursday, so that'll be fairly late.

Ok: Looking at the intermittent failures view, I think it's pretty clear this has indeed fixed this, and there's not been any other problems. I'll nominate this for beta now.

Actually I lied. I started writing the User impact section and came to the conclusion this shouldn't be uplifted and should just ride the trains:

The user impact here should be nothing observable. This is a data race between an Cache-writing thread and a cache-populating write. I think the only outcome here is a script which could perhaps be stored to the cache is not, meaning an infinitesimal slowdown on subsequent startup.

Marking 87 as wontfix.
