;-)

Well I think to create a selector for NIO* is the *best* way.

http://docs.oracle.com/javase/6/docs/api/java/nio/channels/spi/SelectorProvider.html
http://docs.oracle.com/javase/6/docs/api/java/nio/channels/Selector.html

like the

./jdk/src/solaris/classes/sun/nio/ch/EPollSelectorImpl.java

http://hg.openjdk.java.net/jdk6/jdk6/jdk/file/b6c45a8b14fb/src/solaris/native/sun/nio/ch/
http://hg.openjdk.java.net/jdk6/jdk6/jdk/file/b6c45a8b14fb/src/solaris/classes/sun/nio/ch/

I will take a look into this further but without timeline, it's just 
for my curiosity ;-)
