Using id(self) as a void* is wrong in general. It's not incrementing
the reference count. But with ctypes you should almost always ignore
the context parameter of C callbacks. Pass None (i.e. NULL) for the
context. Instead use a bound method as the callable. You'll get the
self reference for free, which gives you all the context that you'll
ever need.
