I'm not sure there is more than that to it. There is at any given time
necessarily a trailing edge system, which is where you tend to run into
trouble if you try to use compiler or library features past some
invisible boundary, and which also tend to have flaky hardware and
perhaps limited resources in general, and so you might also tend to see
some more test instability there.

That used to be an HP-UX 10 system, and then later it was an OpenBSD on
Sparc system, and now it's seemingly this one, and perhaps there were a
few in between, and there will be a new one soon. But this keeps
moving, and the lore from more than 12 months ago is probably not that
useful here.
