> MessagingService's nonblocking io has been a source of bugs both in our code
> and in the JVM in every release of Cassandra. Time to explore moving to
> blocking i/o, which is simpler, more robust (in terms of the JVM
> implementation), and possibly more performant as well
> (http://paultyma.blogspot.com/2008/03/writing-java-multithreaded-servers.html).
