Yeah, I think we do worse, e.g. GC stress tests in tier3, which can hog CPUs for minutes, without ill effects. Not sure if we stress out huge amount of threads.

Anyway, this is similar to other parallelism improvements we did over the previous years, e.g. https://bugs.openjdk.org/browse/JDK-8273433, https://bugs.openjdk.org/browse/JDK-8273438 -- so I gradually continue this one test directory after another :)
