As requested, the protocol now includes memory unpinning support.
This has been implemented in a non-optimized manner, in such a way
that one could devise an LRU or other workload-specific information
on top of the basic mechanism to influence the way unpinning happens
during runtime.
The feature is not yet user-facing, and is thus can only be enable
at compile-time.

Also, is it worth indenting things with extra spaces in your original
series, so that this series (and even future follow-on series) have more
space to use without having to reindent? That is, why not leave room
after your current longest command:
12. Unregister finished (confirmation that unpin completed)
and adjust the remaining lines to line up.
