Running the example from the Asynchronous Mixins section of the “socketserver” documentation generates a ResourceWarning:

$ ./python -btWall
Server loop running in thread: Thread-1
Received: Thread-2: Hello World 1
Received: Thread-3: Hello World 2
Received: Thread-4: Hello World 3
sys:1: ResourceWarning: unclosed <socket.socket fd=3, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('', 43804)>

There is a server_close() method mentioned in the doc string of the BaseServer class, so I assume it is meant to be part of the API. But there is no mention of it in the reference documentation.

I think server.server_close() should be documented, and called after server.shutdown() in the example. A further enhancement might be to turn BaseServer into a context manager, but I would be happy with using the existing server_close() method.

Here is a simple patch to add server_close() to the documentation, and a simple test to ensure it closes the socket.

Left a couple small nitpicks in Rietveld. Otherwise LGTM.

Posting server_close.v2.patch, which tests fileno(), and uses a single space between the new sentences. Also added a bit to the how-to at the top (using doubly-spaced sentences to match the rest of the paragraph).

LGTM. I'm not sure whether or not it's eligible for 3.4 though as it's a documentation and not a functional fix.

In general documentation changes go in all maintained versions (ie: right now that would be 2.7, 3.4, and default/3.5).  The only exception, really, would be if the change didn't apply to one or more of the versions because of code differences.  (Note: I haven't reviewed the patch itself yet ;)
