The use cases I have heard of which would benefit such a feature is
(say) for database threads which want to change their "resource
affinity" status depending on which customer query they are currently handling. If they are handling a query for a "important" customer, they will want affinied
to a high bandwidth resource container and later if they start handling
a less important query they will want to give up this affinity and
instead move to a low-bandwidth container.


hmm, would it not be better to have a thread each in two different
containers for handling different kind of requests.

Its possible but now you're effectively requiring the thread pool to
expand as many times as service levels supported.

any long running job whose prioritization changes during its lifetime
also benefits from being able to be moved.


Or if there is too
much of sharing between threads, then setting the individual priority
should help.
