Check out U of T's Snowflock. Very fast VM cloning and destruction. http://sysweb.cs.toronto.edu/snowflock http://sysweb.cs.toronto.edu/snowflock

  Hundreds of milliseconds, wow. Thanks! Ach, I see now what eru meant by copy-on-write VMs.

    Yes. Booting up every VM would take too long. Cloning them just before you execute the payload is the way to go. (At least as long as you have a general purpose operating system. A special paravirtualised would probably not need to make much of a difference between booting and resuming. But that's only a theoretical musing for your circumstances.)

      Many thanks for the tip. This is my new plan of last resort if I can't prevent the current sandbox from failing.

        Please keep me informed (matthias.goergens@gmail.com) on your progress, if you go this route. Thanks!
