What version of mod_python are you using?

  http://issues.apache.org/jira/browse/MODPYTHON-102

Connection handlers are rarely used so possibly other bugs lurking in
there as well.

I get the impression you are perhaps going about this the wrong way as
you still need XML-RPC/SOAP to work over HTTP and as soon as you use
connection handlers, don't think that is possible as you are
responsible for everything. You are therefore likely better off doing
everything as a request handler. You aren't going to make anything
simpler by using a connection handler.

BTW, look around and you will already find implementations of
XML-RPC/SOAP endpoints for mod_python and newer WSGI interfaces which
can be hosted on mod_wsgi and other WSGI servers. So, you may also be
partly reimplementing the wheel.
