Subject: [PATCH] Fixed a problem with detaching attachments in situations
 where the user's asset server is not the same as the simulator's asset
 server. Unfortunately this still continues to be wasteful -- new assets are
 created every time an attachment is detached, but the process of storing the
 new asset goes through the InventoryAccess module, which does all sorts of
 checks regarding the users' inventory.
