Just wondering why. I understand that the TOC built depends on the current Info file, but I'm wondering why the node list (tree) for a given Info file isn't kept around, to avoid rebuilding it each time a user hits `T'. Just trying to understand the code a bit better - not necessarily suggesting any change is needed.
