Workerware does not work yet due to one of the following possibilities:

1. UV or the bare client is not updated to support workerware yet.
2. Workerware is unfinished.
3. We are doofuses and do not know how to use workerware properly.

Going to implement a ghetto domain blacklist for now.

  debug: true,
  randomNames: true,
  timing: true

ww.use({
  function: event => console.log(event),
  events: ["fetch", "message"]
