Description

The cache tracker, introduced in OAK-4112 allows to avoid locking when updating the document cache.

Apparently, we also track changes made by the local thread. As a result, if we update a large range of documents, the false-positive error rate increases over time, even if there are no other threads running and updating the cache.

We should only track cache updates made by other threads to avoid this.
