Description

This record is used to grab a "snapshot" of a threadpool's internal state.

This is useful in peering into the inner workings of a threadpool for diagnostic purposes. This snapshot may not be strictly accurate because the accessed threadpool continues to run.

Do not depend on this structure for anything other than simply hinting at the internal state.
