-// LLAttachmentsMgr
-//
-// This class manages batching up of requests at two stages of
-// attachment rezzing.
-//
-// First, attachments requested to rez get saved in
-// mPendingAttachments and sent as a single
-// RezMultipleAttachmentsFromInv request. This batching is needed
-// mainly because of weaknessing the UI element->inventory item
-// handling, such that we don't always know when we are requesting
-// multiple items. Now they just pile up and get swept into a single
-// request during the idle loop.
-//
-// Second, after attachments arrive, we need to generate COF links for
-// them. There are both efficiency and UI correctness reasons why it
-// is better to request all the COF links at once and run a single
-// callback after they all complete. Given the vagaries of the
-// attachment system, there is no guarantee that we will get all the
-// attachments we ask for, but we frequently do. So in the common case
-// that all the desired attachments arrive fairly quickly, we generate
-// a single batched request for COF links. If attachments arrive late
-// or not at all, we will still issue COF link requests once a timeout
-// value has been exceeded.
-//
-// To handle attachments that never arrive, we forget about requests
-// that exceed a timeout value.
