I have created [JDK-8370315](https://bugs.openjdk.org/browse/JDK-8370315) on mainline to look into it and also see if/when multiple threads can be beneficial.

Right, I wonder if scenarios should really be parallelized by the framework or if we shouldn't let jtreg take care of that (which has the advantage that it will also parallelize on different hosts, I think).

The changes look good to me.
