[The first part of the message again, this time via the web interface.]

Antoine is right, this needs to be fixed. I think that for *practical*
purposes, the existing release() method already behaves like a tryrelease()
method:


>>> b = bytearray(b'123456789')
>>> m1 = memoryview(b)
>>> m2 = memoryview(m1)
>>> m1.release()
>>> b.append(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
BufferError: Existing exports of data: object cannot be re-sized
>>>


So while m1.release() in fact *does* release a buffer, the desired
effect (freeing up 'b' for subsequent operations) only happens
after also calling m2.release(). This applies to Python and NumPy
objects.
