I debugged JXTG down and found out that seupt() is called twice when you use cocoon://.
There have been problems in the past with xsp pages that were loaded twice when using
cocoon:/(/) protocol

Maybe there is a connection to http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=109419334830100&w=2
WDYT? Are there any paths to follow?
