Accounting badly broken in v1.0.11

If you are having issues with the current release, it is probably  
best to try the svn version.

I can't imagine why chilli would be sending out odd RADIUS half way  
during a session. Is it perhaps not getting any Accounting-Responses  
coming back (and hence you see the retries)?

Accounting-On/Off is a new(er) feature and is per RFC - useful for  
clearing out stale sessions when you know chilli rebooted.
