     6  * The downloads richlistbox may list thousands of items, and it turns out

     7  * XBL binding attachment, and even more so detachment, is a performance hog.

     8  * This hack makes sure we don't apply any binding to inactive items (inactive

     9  * items are history downloads that haven't been in the visible area).

    10  * We can do this because the richlistbox implementation does not interact

    11  * much with the richlistitem binding.  However, this may turn out to have

    12  * some side effects (see bug 828111 for the details).

    13  *

    14  * We might be able to do away with this workaround once bug 653881 is fixed.
