Some NioSocketSession will never be destroied

[Owen Gu]

Please try following testing code, you will find if the NioProcessor counts
are 100, when the server accept and close more than 100 connections, there
will have 100 NioSocketSession instance live forever. Can anyone tells me
why, is this a mina 2.0-m1 bug?
