> When investigating the performance of  {{segment-tar}}, the source of the 
> writes (commits) is a very useful indicator of the cause.
> To better understand which threads are currently writing in the repository 
> and which are blocked on the semaphore, we need to improve 
> {{SegmentNodeStoreStats}} to:
>  * expose the number of commits executed per thread
>  * expose threads currently waiting on the semaphore
