Christian thank you for your reply, i really appreciate it.

Lets analyze this a bit:
- Technically speaking i can "return client" directly and it would NOT close the socket.
- Shouldn't "inside" having reference to same fd mean +1 to reference count. Considering its a new object?
id(client): 140340037397192
id(inside): 140340010863560

I could understand making a duplicate of the fd if it were being passed across thread/process but in its original thread making a duplicate! This behavior is extremely odd.

I fell like everyone that uses socket(fileno) will run into days wasted and frustration just to figure out these solutions.
