Cool, but arguably a layering violation. It's the job of the operating system.
- astrodust 11y ago
  Define "operating system"? It's not crazy to think that you might have another layer inside your VM, not unlike how a hypervisor was one layer that didn't exist outside of mainframes until adapted for regular computers.

  In a world of unikernels and library OSes, that is the job of the runtime.
  - andor 11y ago
    Not necessarily. One of the ideas behind unikernels is very fast boot time, so that you can start a new instance for every tenant. Another idea is reduced complexity...

      In which the OS and language runtime are the same thing, e.g. Mirage OS.

  Very cool. I was still writing assembly at college at the time.
