Looking at the list of processes should be enough.

Having a test case with only llvm would help upstream too.

No, I haven't find the time to work on this and probably won't as it doesn't occur much.
However, I would be happy to apply a patch for this.

If you can help, sure.
Here, we should not list all the tests (too many of them). We should instead dump the list of tests being executed when the testsuite is killed.

I stand by my initial decision. I am building the LLVM toolchain twice a day on 2 architectures for 8 Debian/Ubuntu releases + maintain Debian packages.
I think the process is reliable enough for Debian.

However, as I said, I am happy to apply any patch to help you in your goals.
