The basic approach is to add all the file texts into the

store, then the inventory, then make a new revision pointing
489
to that inventory and store that.
491
This is not quite safe if the working copy changes during the

commit; for the moment that is simply not allowed. A better
493
approach is to make a temporary copy of the files before
494
computing their hashes, and then add those hashes in turn to
495
the inventory. This should mean at least that there are no
496
broken hash pointers. There is no way we can get a snapshot

of the whole directory at an instant. This would also have to

be robust against files disappearing, moving, etc. So the

whole thing is a bit hard.
