Do we want hard coded `IncWorkWeighted(2)` here or do we want to switch to the approach you used in [lines 171-172](https://github.com/basho/leveldb/blob/1b3b6ab35eb794e51eefee131c2ac04542c489fd/util/hot_threads.cc#L171-L172):

```c++
m_Pool.IncWorkWeighted(Env::Default()->NowMicros()
                       - submission->m_QueueStart);
```
