> Hmm... _decref_socketios() is not really a public API.  I think it would be nice to have an official way to deal with this, and a socket close callback sounds reasonable to me.


We can just make it public (after some renames) :)  My first idea was to add a refcounting API to sockets, I just didn't know it's already there (I assumed that socketmodule.c implements the actual 'socket' object, and never even looked in socket.py module).

I'll experiment with this stuff in asyncio/uvloop and report back to this issue.
