1767 *
1768 * In order to achieve this, we compare the analyser
1769 * list after the call with a copy of it before the
1770 * call. The work list is fed with analyser bits that
1771 * appeared during the call. Then we compare previous
1772 * work list with the new one, and check the bits that

1775 * analyser and must immediately loop again.
