Reassuring that it's not my hardware that has gone faulty :)

It still appears to run pretty hot, case temperature around 38C ...
I didn't measure it with 2.0, so I wouldn't know if it's significantly
better, but it's still too warm to keep in the lap.

Oh, I wasn't aware of that. I'll try that one, thanks.

Even without explicit v8 optimisation, ssh appears to be a lot
faster on -current than it was on 2.0. My gut feeling says about
twice as fast, but I may be wrong.

But if it's a general problem with randomly dying processes, I
might as well stick with my own builds. I thought maybe my snapshot
was particularly flaky.
