I have checked following projects.

regex, simplejson, Pillow, PyQt4, LibreOffice, PyGTK, PyICU, pyOpenSSL, 
libxml2, Boost, psutil, mercurial don't use PyObject_SetAttr at all.

NumPy, pgobject don't use PyObject_SetAttr for deleting.

PyYAML and lxml use PyObject_SetAttr only in code generated by Cython 
and never use it for deleting.
