OK, I make some slight modifications and applied the attached patch.

Ideally we could tell everyone to read the developer's FAQ, but that is
too large for people who are debugging problems in our shipped code ---
that is why I was excited to get something into our main docs.

The value is only needed by te worker, so there is no need to store it in
shared memory.
