Because :
- the SSLSocket has a strong reference to the ssl object (self._sslobj)
- self._sslobj having a strong reference to the SSLSocket would mean 
both would only get destroyed on a GC collection

I assume that's what "leak" means here :-)

As for 2.x, I don't see why you couldn't just continue using a strong 
reference.
