The suggestion came from folks working on asyncio performance
improvements, and we already got the entire ``selectors`` abstraction
from the original asyncio implementation work, as well as Yury's new
libuv-based ``uvloop`` asyncio event loop implementation.

Given that "make OpenStack/SDN/NFV run faster" is a key point of
interest for folks like Intel and Red Hat, I'm *absolutely* suggesting
that they put some paid time and energy into a lower level buffer
manipulation library between now and the Python 3.7 feature freeze in
12+ months, as I think that will have longer term pay-offs well beyond
the scope of the original use cases :)
