In 2.7, we currently get the buffer with bf_getreadbuffer. In 3.x, we have
/* Release the buffer immediately --- possibly dangerous
but doing something else would require some re-factoring
*/
PyBuffer_Release(&view);
Even if we do use the new API, and correctly, it still might be
confusing if the contents of the buffer changes underneath.
