1770 * it immediately, even if it has already been called
1771 * once but removed since.
1772 *
1773 * In order to achieve this, we compare the analyser
1774 * list after the call with a copy of it before the
1775 * call. The work list is fed with analyser bits that
1776 * appeared during the call. Then we compare previous
1777 * work list with the new one, and check the bits that
1778 * appeared. If the lowest of these bits is lower than
