Thanks. I really hadn't followed that.

I understand that better now.

However, if if there is still a reference to the buffer object, is that 
memory still good? It looks like it is:

 >>> b[0]
'a'
 >>> b[5]
'a'

That makes it look to me like the buffer object is responsible for that 
memory, and if it's reference count > 0, then is will keep it around.
