Didn&#x27;t containers just create a sandbox for the code to run? If they get a full VM, what is the difference between containers and old style VMs?<p>Anyway, I don&#x27;t have experience on Go or V8 Javascript, but C pthreads, Haskell threads and Python threads all just encapsulate the OS functionality to add some conveniences. Java does come with a complete threading implementation, and gets no lack on criticism because of that. You may get away running Node on a single task kernel, but Postgres will simply refuse to load if it can not fork some processes and talk to them by shared memory. Apache&#x27;s behavior is similar.
