Are there plans for adding concurrent or parallel execution to the test runner? I recently tried looking at the code base to maybe implement it myself, and it looks like it wouldn't be easy without some reworks.

We need to do some form of this but I’m not exactly sure what yet. I suspect same process but multiple globals might work well. A lot of tests spend time sleeping or waiting for things. They might benefit from that kind of paralellism (like async/await, except between things it runs a whole other global object)

Threads could also work but the problem is you have to re parse & evaluate all the code. That’s a lot of duplicate work. It’s probably still worth it for large enough apps

Isn't there some way of cloning a loaded vm after loading a module? I would imagine that should be possible some how, that way you could parse once then execute in multiple threads.
