> When running requests on a local transport configured with DISPATCH_DIRECT = true, small request/response messages process successfully but any request that generates a response > 1KB seems to hang the JVM. The problem appears to be in the PipedInput/OutputStreams. If the buffer (default size 1024B) fills up it is never flushed and the thread appears to hang in an eternal wait (PipedInputStream.awaitSpace())
> The PipedInput and PipedOutput Streams are on the same thread and therefore the buffer is never cleared until after the stream is closed. Pipes should never be used on a single thread. That will definitely cause a hang. Possibly should use a CachedOutputStream and then grab the inputstream in the dispatchDirect method.
