I second this. I had to implement this and then use it for the first
time ;-)
It is good to be forced to think about your code in all possible ways.
Most of the time (IMHO) if you can't get it done with coop
multithreading, you surely are not up to
doing it preemptive. You just don't see your race conditions...

Java added non-blocking I./O in 1.4 to facilitate writing
high-performance network services.
Because it is an easier programming model etc. ;-)
