Summary: popen2 returns (out, in) not (in, out)

Initial Comment:
http://python.org/doc/current/lib/os-newstreams.html#l2h-1379
says:

popen2(  	cmd[, mode[, bufsize]])
    Executes cmd as a sub-process.
    Returns the file objects (child_stdin, child_stdout). 

But for me it actually returns (child-output, child-input).
Or... is it a semantci issue?  that is 
  child_stdin - is "the input _from_ child?"
Anyway - it is confusing.

The above is not-a-bug, but this documentation patch below
might serve to remove any confusion.

+It should be noted that \code{\var{child_stdin},
\var{child_stdout}, and
+\var{child_stderr}} are named from the child process' point
of view, i.e. the
+stdin of the child.
+
 This functionality is also available in the
\refmodule{popen2} module
 using functions of the same names, but the return values of
those
 functions have a different order.
