Random PeriodicInformInterval doesn't work as expected

[Dan Morphis]

Two questions, why do you want an interval so low, and why do you want a
random interval? Load?

Looking through sandbox.js we see this:

// Monkey-patch Math.random() to make it deterministic
context.random = random;
vm.runInContext("Math.random = random;", context);
delete context.random;

And random is defined as:
function random() {
  if (!state.rng)
    state.rng = seedrandom(state.sessionContext.deviceId);

  return state.rng();
}

random.seed = function(s) {
  state.rng = seedrandom(s);
}

This means for that particular device id, you will always get the same
"random" value
