Description

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
