The answer comes from the NEXT version of the docs, quoted below
(thanks Fred) ;-)
When memory buffers are passed as parameters to supply data to build
objects, as for the \samp{s} and \samp{s#} formats, the required data
is copied. Buffers provided by the caller are never referenced by the
objects created by \cfunction{Py_BuildValue()}.
