[mod_python] import error

Does renaming your xml.py (and changing httpd.conf accordingly) to  
anything but 'xml.py' help?

Just a wild guess: apache.import_module first tries to load the  
modules named 'xml', looking for it at sys.path, which happens to  
include /home/becker/framework_python_web. It finds your handler  
script (named xml.py), thinks it's the 'xml' module, reads it,  
stumbles upon the very same import statement it's currently  
executing, and promptly dies and report an import cycle.
