Re: AbstractSelectableChannel

Hum, perhaps we should try a async emulation layer
instead of using nio. 
There is a true async implementation from IBM that
could solve the known problem of scalability (C10K
problem).
But I dont think we can use on this project (maybe
because of licensing issues, but need to check it
anyway).

And, we can try Coconut AIO emulation layer. It seems
to be pretty interesting implementation that could
enhance seda performance.

See: http://coconut.codehaus.org/Coconut+AIO
There is only a concern: It must be run on JDK 5.
