Exactly. The same code raises a socket.error in one platform (mac os) and not on another (linux). Why not document this questionable behavior?

I'm sorry, I realize that my original patch was imprecise. I'm not an expert here, and I simply read http://svn.python.org/view/python/trunk/Lib/test/test_socket.py?r1=64125&r2=68611&pathrev=68611 . Ok, fine -- it doesn't close the other end per se, but shutdown(SH_RD) after a FIN on MacOS raises a socket.error . This is questionable, unexpected, and should be documented.


If possible, I'd like to push for a rewording instead of a revert.
