Asynchronous behaviour with CXF endpoint for SOAP services

Issue

• Please provide some insights in to the asynchronous/synchronous behaviour of cxf:endpoint for receiving the soap requests.
• My first question is , what is the default invocation mechanism for cxf:endpoint server and client service ? Does the cxf:endpoint serve the request in an asynchronous manner by default ? I have the following route

<route id="RECIEVER_MODULE">
            <from uri="cxf:bean:CURRENCY_EXCHANGE_RATE" />
            <log message="RECIEVING MODULE SECTION ${body}" loggingLevel="INFO"
                logName="INPUT" />
            <delay>
                <constant>10000</constant>
            </delay>
            <to uri="file:c:\\input1" />
        </route>

• From SOAPUI i have triggered one request and the thread waited for 10008 millisecs. On debugging I found that its waiting in the following piece of code

private Object asyncInvoke(org.apache.cxf.message.Exchange cxfExchange, final Continuation continuation)
      {
        synchronized (continuation)
        {
          if (continuation.isNew())
          {
            final org.apache.camel.Exchange camelExchange = perpareCamelExchange(cxfExchange);

            CxfConsumer.LOG.trace("Suspending continuation of exchangeId: {}", camelExchange.getExchangeId());

            continuation.suspend(0L);

            CxfConsumer.this.getAsyncProcessor().process(camelExchange, new AsyncCallback()
            {
              public void done(boolean doneSync)
              {
                synchronized (continuation)
                {
                  CxfConsumer.LOG.trace("Resuming continuation of exchangeId: {}", camelExchange.getExchangeId());

                  continuation.setObject(camelExchange);
                  continuation.resume();
                }
              }
            });
          }
          else if (continuation.isResumed())
          {
            org.apache.camel.Exchange camelExchange = (org.apache.camel.Exchange)continuation.getObject();

            setResponseBack(cxfExchange, camelExchange);
          }
        }
        return null;
      }

• continuation.suspend(0L) suspend the incoming thread , and the request thread needs to wait for the doneSync value to be true. I want to handle the request in an asynchronous manner , ie I dont want the client to wait for the route processing to complete.The thread should be released at the same moment it send the request from SOAPUi ?
