[RFE] new procedure method

i don't know if the following if possible but that would be handy to
have.

in procedure calls we have abort(message) which raise an error.

i think it would be useful if we have other means to send message which
would not be errors.
Something like: info(message), the difference being it would not raise
an error in python. Maybe create an xmlrpclib.Fault with a special code
or... i don't know.

another useful thing would be a confirm method, bool = confirm(message),
which could be used to ask users for a boolean answer (Yes/No). I don't
know if this one is even possible, cause it'd have to stop the execution
of a procedure and then resume when the client answer (maybe use a
separate thread...).

any thougths?
