I cannot import it unless a corresponding extension
implementation is plugined underneath the Python VM.

Indeed, but I can "import signal" or "import socket"
wherever I go, without worrying about requiring (or
worse yet, having to bundle) a CPython plugin
(presuming I am even running on top of CPython).
I am hoping for something which does not require
a context switch (or worse) for every wait/notify.
