Introduced in: elastic#90536 Profiling for DFS has had its timing numbers looking weird, additionally, it would trigger some assertion failures because `timer.start()` was called without a `stop()` in between. The key issue was around query `weight` creation. `Weight` creation could be called recursively, thus calling `start` on the timer more than once before calling stop.
