SecureXMLRPCServer module using pyOpenSSL 0.5
Extremely kludgey code written 0907.2002
by Michal Wallace ( http://www.sabren.net/ )
This acts as a drop-in replacement for
SimpleXMLRPCServer from the standard python
library.
This code is in the public domain and is
provided AS-IS WITH NO WARRANTY WHATSOEVER.

"""
SSL Connection tends to die on sendall,
so I use send() as a workaround. This is
called by socket._fileobject, which is needed
so SocketServer (and kids) can treat the connection
as a regular file.
"""
def __init__(self, conn):
"""
For some reason, I can't subclass Connection,
so I'm making a proxy, instead.

This isn't part of the bugfix. SimpleXMLRpcServer.doPOST
calls shutdown(1), and Connection.shutdown() doesn't take
an argument. So we just discard it:

This is the other part of the shutdown() workaround.
Since servers create new sockets, we have to infect
them with our magic. :)
