Looks like some background threads are not getting created as daemons.
HostConfig calls thread.setDaemon(true) after creating its background
thread (as well as setting the thread name), so it doesn't look like that
is the culprit.

Does Apache SOAP try to create background threads without cleaning them
up afterwards?  Or, maybe the XML parser it's using?
