Subject: From: Christopher Yeoh <cyeoh@au1.ibm.com>

Attached is a patch which fixes mantis bug 2645 where scripts in child
prims
freeze after being unlinked from the root prim. This got introduced
some time after the 0.6 freeze. Have checked test suites
pass even after nant clean  ;-)

http://opensimulator.org/mantis/bug_update_page.php?bug_id=2645

Also removes a redundant ResetIDs call

Regards,

Chris
