I don't quite see what your problem is. Of course the chunks need to be generated when you start the server and the world doesn't contain them. There's no duplicates in your list, so I really don't know what you're complaining about.
CPU at 100 % is quite right when generating chunks, supposing you have a single-core machine. The chunk generating thread is running at full speed. Once it stops generating chunks, your CPU usage should drop.
oh, I see now. When the chunk is generated, it is not marked dirty, therefore not saved until you actually make a change to it. I'll fix that.
