Recursion Depth
A threal local counter, incremented whenever a log statement is being processed by the backend. If this value is greater than 1, then reentrant logging has occured, and some code may behave differently to try and avoid issues such as unbounded recursion. Logging may even be disabled completely if the depth gets too high.
This class is an internal detail and must not be used outside the core Flogger library. Backends which need to know the recursion depth for any reason should call
Platform.getCurrentRecursionDepth().
