public class BigPipedInputStream
extends java.io.PipedInputStream

We are now Java 6 minimum. Just use PipedInputStream. Java 1.5 PipedInputStream buffers are only 1024 bytes; our I2CP messages are typically 1730 bytes, thus causing thread blockage before the whole message is transferred. We can specify buffer size in 1.6 but not in 1.5. Until we switch to Java 1.6 - http://javatechniques.com/blog/low-memory-deep-copy-technique-for-java-objects/ Moved from InternalServerSocket.
