| 1692 | * on the loop. If it removes any other analysers, we |
| 1693 | * want those analysers not to be called anymore during |

| 1695 | * after itself, we want it to be scheduled for being |
| 1696 | * processed during the loop. If it adds an analyser |
| 1697 | * which is located before it, we want it to switch to |

| 1703 | * call. The work list is fed with analyser bits that |
| 1704 | * appeared during the call. Then we compare previous |
| 1705 | * work list with the new one, and check the bits that |
| 1706 | * appeared. If the lowest of these bits is lower than |
| 1707 | * the current bit, it means we have enabled a previous |
| 1708 | * analyser and must immediately loop again. |
