The bindings are just not complete.  I would love to get patches from
someone.  Basically what I would like to see is the ability to pass in 
a callback when invoking a method.  Don't know how this could best be
done.  Basically if a callback is set to anything other than None, the
call will not block.  

Keep in mind I want to do an overhaul of the bindings at some point so
if you see a better way we can structure things let me know.  Right now
I am stuck trying to get the bindings to compile with gcc 4.0 so I
haven't been hacking on functionality all that much.  If you are
offering to help that would be great.
