This looks very much like an error mentioned in the wiki (on the page you 
referenced above).  Does it always occur in the same place?  Have you tried 
running in a different shell, or logging off and back on?  If the error 
doesn't always occur or if it occurs at different places in the test 
sequence, it is probably the error discussed in the wiki.  I find it does 
not usually cause problems in normal use.  The only way I know to avoid it 
is to patch Python and rebuild it from source.
