The standard modules need to be redesigned! And M2Crypto would have
to be the standard SSL. And as I state in the first paragraph you quote,
it has to subvert the existing classes. Think of my code as the
result of using chainsaws and band-aids all over the existing code.
The end result works fine for me and my project. But I wouldn't
remotely want to change the existing library to anything like it.

Here were the goals I was trying to meet. The current Python library
does not remotely meet them.

XML-RPC client:

   - Connections are made over SSL
   - A callback to verify the certificate if there is no
     CA or other defined mechanism
   - HTTP/1.1 is used, and the connection is reused if
     still open
   - HTTP authentication is used
   - Automatic reopen of connection if above one doesn't
     work (eg remote end closed it after timeout)
   - Be thread safe (eg one connection per thread - don't
     reuse across threads)

XML-RPC server:

   - Connections are accepted over SSL
   - Callbacks to verify incoming connections, certificates and
     credentials of the connections
   - Verification of HTTP authentication information
   - Connections are kept open/keep-alive (HTTP/1.1)
   - Use of a bounded thread pool that handles the connections
