xml-rpc/twisted question

[Guyon Morée]

Hi all,

Below this message you can see my code. It is a modified version of the
twisted xml-rpc server examples. I am trying to figure out how to implement
non-blocking methods. I found out that I have to use 'defer' to do that, but
I have no clue how to do this. Unfortunately the documentation could not
make this clear to(unless I am missing some docs). I have already added a
function called xmlrpc_block to represent a actual 'blocking function'.

I hope someone can show me how to modify this so the server does not block
any other clients when xmlrpc_block is called.

thanx,
Guyon
