> The data in the Segment Store doesn't provide any information about the 
> dynamic behaviour of the system. For example, who performed the commit? How 
> many commits were performed from the same committer?
> In order to simplify debugging the dynamic behaviour of a system, it should 
> be possible to store metadata about the commit in the super-root generated by 
> that commit. For example, the following information might be attached to the 
> super-root:
> * The name of the thread performing the commit. This solution might prove 
> expensive in terms of consumed disk space, but would be the most precise tool 
> to identify the author of a commit.
> * A hash of the thread name. If storing thread names proves expensive, a hash 
> of the thread name can be stored instead. This doesn't allow to exactly 
> identify the author of the commit, but would allow us to correlated different 
> commits as performed by the same thread.
> * Both the thread name and its hash, with the thread name stored only every 
> Nth commit. This solution is not as precise as storing the thread name for 
> every commit but, if there is a frequent committer, its thread name will be 
> more likely to be sampled, thus providing a precise identity to a thread name 
> hash.
