> 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.
