Work queues

[Benson Margulies]

https://karaf.apache.org/manual/latest/users-guide/tuning.html claims
that CXF uses work queues. I googled for 'cxf work queues', but didn't
end up illuminated. In an ordinary JAX-RS service, are work queues
involved, or is it something I need to configure? For that matter, why
would I want to configure it?
