The above code was submitted to Python's SF patch collector on
2001-Jan-19:

    http://mail.python.org/pipermail/patches/2001-January/003581.html

and was committed to Python CVS on 2001-Jan-24:

    http://sf.net/tracker/?group_id=5470&atid=305470&func=detail&aid=402409

On 2002-Jun-11, the AtheOS port began to leverage it:

to Python's SF patch collector to change to the behavior to be more to
your liking.
