Say a worker invokes importScripts(). That invokes the service worker.
In the service worker a field named "client" is exposed in either the
event or the Request object associated with the event. That "client"
holds a message channel for the worker.

It's equivalent in a document environment with an <img> or a
background-image in an associated style sheet.
