Yes, got that, but it would be scanning the world file to determine what had updates available that had not been performed. If some of the updates were at the same moment being performed in another instance, that is not likely to confuse Portage as to whether an update to konqueror (for example) was available or not (if konqueror was at that moment being upgraded in the other console)? > Emerging KDE only results in one write to world, at the end of the > process. I suppose, if you're only emerging kde-meta (since all the sub-builds are dependencies that will not be added to your world file.

Also possible. Certainly there's nothing /wrong/ with running emaint --check world. I only wanted to point out that this error could also be a "false positive".
