I eventually tracked this down to xmlrpc changes in python 2.7 . The patch
below fixes the xm problem, and a xend problem serving xmlrpc. Note that
the first part won't work as written with earlier versions of python,
though the second part is probably safe as disable_nagle_algorithm was
introduced in python 2.7.
