    Please try to read and understand the patches, before
    imagining that they might not be enough.

    The active file list is kept at least as large as
    the inactive file list. Your backup is one large
    streaming IO. This means the files touched by
    your backup should go onto the inactive file list
    and get reclaimed, without putting pressure on
    the active file list.

    If you are still not convinced that these (small)
    changes are enough, please test the patches and
    show us the results, so we can tweak things further.
