[Cython] __dealloc__ called even if __cinit__ failed

I'm not entirely sure if this is a feature or bug...

I noticed that, if a __cinit__ call raises an exception on an object, 
that __dealloc__ on that same object is still called.

The problem is that __cinit__ is supposed to set up the C-level 
attributes for that object. If this somehow fails, then the object isn't 
in a consistent state yet, so it makes no sense to call __dealloc__ on it.

Do you consider this a Cython bug or should I manually protect my code 
against this?
