    Lets pull in this patch from freebsd:
    http://svnweb.freebsd.org/base?view=revision&revision=271781
    bpobj_iterate_impl(): Close a refcount leak iterating on a sublist.
    If bpobj_space() returned non-zero here, the sublist would have been
    left open, along with the bonus buffer hold it requires. This call
    does not invoke any calls to bpobj_close() itself.
    This bug doesn't have any known vector, but was found on inspection.

    Fix bpobj_iterate_impl() to properly call bpobj_close() if bpobj_space()
    returns an error.
