    Prevent endless loop on pool cleanup

    When APR_POOL_DEBUG is set, we check up to three levels deep for a
    kind of corruption of the cleanup lists where a node is duplicated
    causing an endless loop and abort.

    If we hit this class of corruption when not debugging, however, we'd
    prefer to just ignore it in preference to looping infinitely or

    With this change, we check for immediate duplicates and simply stop
    processing the cleanup list at that point potentially leaking
