Tomcat with NIO???

[Cin Lung]

Is this real? I found this tomcat setting from the following site:
http://www.javalobby.org/java/forums/t92965.html
 
Here is the setting (see the higlighted part):
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" connectionTimeout="20000" acceptorThreadCount="2"
redirectPort="8443" socket.directBuffer="false"/>
 
Is this mean that there is a tomcat version that uses NIO? Or maybe is this
a tweak?
 
Any comments.
 
TIA
