Comment (by SimonKing):
PS: I am doing this change now. Also, I am changing `__init__` into
`__cinit__`.
Rationale: The current `__init__` just sets the pointer `self.head =
NULL`. But initialising c-data (pointers etc.) is the job of `__cinit__`:
It should initialise the c-data to such extend that `__dealloc__` can not
crash. With the current code, there may be circumstances under which the
`__init__` is not called, so that `__dealloc__` will fail with a
segmentation fault.
