Yes it surely is

  My "htop" display surely disagrees. So do my node programs that lag out waiting for disk IO thread pool slots. Sounds does node's documentation: https://nodejs.org/api/worker_threads.html https://nodejs.org/api/worker_threads.html

  It's not exactly. Certain operations like I/O are threaded in Node. libuv has it's own threadpool that it uses for a lot of these types of tasks.
