One question: Is there any expected time-frame for freelists to support cdef subclasses? Soon? Never? Somewhere in between?

Hard to say. This isn't easy as supporting subtypes means that we need full control over what the parent types are doing in their allocation/deallocation chain, and that may not be entirely trivial to determine. The current call chain isn't made for that. In any case, no-one's currently working on this AFAIK. Stefan
