I've never used that code, we don't have example code nor a test for it. So as 
always I would argue: Untested code is broken code.

I think we need to implement a test to actually fix the code. However I don't 
have time for this. Contributions in this area are very welcome.

See the server testing code Anderson implemented for a start.


Best regards,
