Bug reference:      13896
Logged by:          Dickson S. Guedes

Description:

>From docs [1]:

    "The worker_spi contrib module contains a working example, which
demonstrates some useful techniques."

But, since commit 22dfd116a127a2fc916a4fdac282ee69d4905a25, 'worker_spi' is
no longer a contrib
module [1], and was moved to test modules, so I think that line could be
removed from docs or point
to new place.
