+ The number of threads being tracked for activities such as waiting for a |
+ lock/event, a thread to join, or a task to run. Analysis of this data can |
+ reveal why a thread will not exit. This value is updated every time a new |
+ thread gets an activity tracked for the first time so will show one count |
+ for every permanent thread but multiple counts for a thread than exits and |
+ is replaced. |

+ persistent memory segment. Trackers beyond this number were allocated from |
+ the heap and thus were not available for analysis. This value is updated on |
