Both PEP 574 and Davin's shared-memory work build on top of the
PEP 3118 buffer API.  So I would expect that any Python implementation
with support for the buffer API to have the required infrastructure
to also support those initiatives.  The details may deserve to be
clarified, though. I'll try to send an e-mail and ask for feedback.
