371 | 3664 * Garbage collection for lists and dictionaries. |
3665 * | |
3666 * We use reference counts to be able to free most items right away when they | |
3667 * are no longer used. But for composite items it's possible that it becomes | |
3668 * unused while the reference count is > 0: When there is a recursive | |
3669 * reference. Example: | |
3670 * :let l = [1, 2, 3] | |
3671 * :let d = {9: l} | |
3672 * :let l[1] = d | |
3673 * | |
3674 * Since this is quite unusual we handle this with garbage collection: every | |
3675 * once in a while find out which lists and dicts are not referenced from any | |
3676 * variable. | |
3677 * | |
3678 * Here is a good reference text about garbage collection (refers to Python | |
3679 * but it applies to all reference-counting mechanisms): | |
3680 * http://python.ca/nas/python/gc/ | |
3681 */ | |

3684 * Do garbage collection for lists and dicts. | |
