According to the Node 11 docs, worker threads are more lightweight than processes, but still heavy.

That makes me think they run in the same address space, but use separate runtimes. So it's more scalable than ruby and python threads or multiprocessing.

JRuby doesn't have a GIL to begin with so there's no requirement to use multiprocessing to host Rails apps etc.

They're an improvement over a single GIL but not by much. IIUC, they're like Racket's Places: a complete duplication of the VM but sharing an address space. The basic implementation doesn't really save much memory but it's a bit more convenient.

There's been a couple of attempts to implement subinterpreters for CRuby too.

JRuby is an incredibly underrated piece of kit. That startup time, though...
