He did, at a high level. in the original mail:

"If code objects supported the buffer protocol it would be possible to load
 code from a memory mapped file which is shared across all of the processes."


It is not very detailed, but gives the rationale.  I assumed that the
new shared memory support would be used, but it would be nice to hear
more details.
