Hi,

This library looks really cool. Unfortunately I hit a snag when I try to use 'immutable'. For example:

  await start();

  const res1 = await job(() => {
    let i = 0;
    for (i = 0; i < 1000000; i++) {}
    let config = OrderedMap(fromJS({}));
    return i;
  });

In the above example, it fails immediately with "immutable_1 is not defined". Is this a known limitation due to the way Immutable was written (using factories)?
Thanks!
