    Description

      Define a new marker interface java.lang.NonTearable which instruction the JVM to enforce atomicity of all instances (in the heap) of the given inline class.

      Any inline class that implements this interface (directly or indirectly) is protected by the JVM from structure tearing, even if this costs some performance.
