Sorry, I wasn't clear.  It fails immediately.  The timeout isn't observed. 

    >> makefile([mode, [bufsize]]) -- return a file object for the socket [*]\n\

Maybe _socket shouldn't have such a detailed doc string or should indicate
its subservient relationship to socket?  I was reading it as if it was a
comment in the code, which, in theory, should still be accurate.

I'll take a look.  There's a bug already in the system
(http://www.python.org/sf/707074) to which a patch could be applied, so if
someone comes up with something, that's where it goes.
