One more question?  What is the reason for separate read/write getbuffer 
calls.  What is the problem with just one getbuffer call with a flag to 
indicate whether or not you want a writeable memory area?

I prefer fewer function pointers because it means that extension types 
must implement fewer functions.  But, either way.

I know there is some stylistic distaste for "flags" in APIs.  One could 
still keep two C-API calls for getting read-only and writeable buffers.
