if you look deeper under the hood of Java NET/IO you will see that there is no configurable timeout for writing blocking IO. The best thing you can do is upgrade to Tomcat 6, and use the NIO connector (protocol="org.apache.coyote.http11.Http11NioProtocol") as that has a configurable timeout for writing data.
