To some degree that revalidates my interpretation of Andreas'
statements. If I understand it correctly eacht time a shell command is
executed, which requires tree interaction, the corresponding tree is
read from filesystem to memory completely before anything is done? So
if I git-add a file, the whole index is read first, then the memory
object is changed and then the resulting change is written to disk
bottom-up from the point of view of the tree?
