Thread hangs when processing response message using LocalTransport with dispatchDirect
--------------------------------------------------------------------------------------

                 Key: CXF-1245
                 URL: https://issues.apache.org/jira/browse/CXF-1245
             Project: CXF
          Issue Type: Bug
          Components: Transports
    Affects Versions: 2.0.3
            Reporter: Michael Coogan


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.
