We plan to ship a "worker" process that will run ServiceWorker (and
eventually SharedWorker) threads as part of:

https://bugzilla.mozilla.org/show_bug.cgi?id=1231208

In the future we may optionally schedule workers in other content
processes, but we are aiming for a separate process to start for a couple
reasons.  It ensures we have no accidental dependencies on running in the
same process as the content page.  It also helps us work around perf issues
with many operations requiring the main thread which is often busy during
page load in content processes.

I also think it would be worth investigating a separate process for the
network stack:

https://bugzilla.mozilla.org/show_bug.cgi?id=1322426

I don't think anyone is working on that, though.
