[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

Another idea we may want to revisit is the PyManagedBuffer concept, which would be a true PyObject that existed solely to simplify sharing of Py_buffer structs.

If memoryview used such an object internally, then copying and slicing would be quite simple - just INCREF the managed buffer instance without letting the original source object know anything was going on.
