I'd be happy to discuss our thought about List inefficiencies, but I think to be fair to Miroslav, we should do that somewhere else. The list_copy_head() discussion was directly related to his patch due to the list of list_truncate(list_copy(..), ..). The other things you've mentioned are not. Feel free to start a thread and copy me in. David
