# Fix for #2705. levelIter encounters two files where the first has seqnum
# below snapshot seqnum, so obsolete points can be hidden. The second file has
# a more recent seqnum so obsolete points cannot be hidden. But the in-place
# modification of the filters slice was causing obsolete points to be hidden
# in the second file.
