> Hmmn. We're still on orthogonal perspectives as far as our previous arguments stand. But it doesn't matter because while thinking through your replies, I realized there is one argument in favour, which trumps all my previous arguments against this patch - it makes things deterministic. Without this patch (or hangcheck), whether a context gets nuked depends on what else is running. And that's a recipe for confused support emails.

No worries, it's been really useful, especially realising a few more
areas we can improve our resilience. You will get your way eventually.
(But what did it cost? Everything.)
