per session attributes

["Trustin Lee (이희승)"]

Hi falconair,

myAttr (i.e. a ChannelLocal instance) is supposed to be accessible from
any handlers, so I would expose it as a public static final member
variable of some class.  For example:

    public class MyChannelAttrs {
        public static final ChannelLocal<String> myAttr = ...;
    }

HTH,
Trustin
