[chord] The question about Chord system

[Zhiyuan Tan]

Dear Chord Developers,

In your papers, you mentioned that the keys held by a node will  be 
relocated to it predecessor when it leave Chord network, but if no one 
else has the objects (represented by the keys), or if there is some 
nodes have the objects but not its predecessor what will happen?

That is the question confusing me all the time?

Could you help me out?

Best regard,

Thomas
