The only outstanding spinning issue we have with the epoll Selector is 
6693490. I hope to get this fixed in jdk7 soon (it's a complex issue 
that arises when the pre-close file descriptor gets registered with the 
epoll in error).

Does it happen if you use the poll based Selector 
(-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider)?
