Unexpected exception in the selector loop

[Shay Banon]

I think I know what might have caused this by analyzing what I changed
recently, though I have not fully gone through the netty code to understand
why this might happen.

It seems like this might happen (not all the time) when I close a channel
from within a channel future listener registered when closing another
channel :). Seems like when I don't do that, I don't get the sporadic
cancelled key exception.

I will try and do more tests and see if this is really the case.
