[Spread-users] Non-unique private name

[Ryan Caudy]

Are you sure Spread is getting your disconnect, and processing it? 
Please add GROUPS and SESSION trace, and let me know what you see. 
When Spread gets a disconnect message from a client, it sends it via
and AGREED message.  When it processes the AGREED message after
receiving it, the name should be reusable.

Cheers,
Ryan
