Modified class

Description of problem:

When calling web services from a client, and using WS-Security, there is a generated chunk for every tag inside the XML document, causing excesive fragmentation. This chunk is generated due to an unnecesary flush in org.jboss.common.DOMWriter. See attached the modified class.
In the modified class there is also a new system property domwriter.flush in order to be able to activate/deactivate the change with the option -Ddomwriter.flush

Version-Release number of selected component (if applicable):

jbossws-common.jar included in JBoss EAP 5.x

How reproducible:

Create a web service and capture network packets in order to see the fragmentation. I also attach pcap files showing the problem.
