I think they are the same in practice: if you lose a reference to a CudaArray, it can be gc()ed; since that eliminates the reference to the pointer, it too can be gc()ed and that causes the memory to be freed. It's just a little more direct with a CudaPitchedArray.

However, I agree it's a little confusing to have these behave differently. Feel free to clean it up and submit a PR.

Can't I keep a pointer myself, while dropping a reference to the array? If the pointer gets freed anyway, that's a problem.

I think only the pointers (wrappers around Ptr{Void}), coming from malloc* should have finalizers, that way there's no problem with mysterious clean up mechanics.

That would be reasonable.
