-// into a tug of war with some other sequence of events that's in the
-// process of adding the attachment in question. However, it's needed
-// because we have no definitive source of authority for what things
-// are actually supposed to be attached. Scripts, run on the server
-// side, can remove an attachment without our expecting it. If this
-// happens to an attachment that's just been added, then the COF link
-// creation may still be in flight, and we will have to delete the
-// link after it shows up.
-//
-// Note that we only flag items for possible link removal if they have
-// been previously detached. This means that an attachment failure
-// will leave the link in the COF, where it will hopefully resolve
-// correctly on relog.
