When doing a STEP_OVER, the debug agent does a NotifyFramePop() on the current frame as a safety net. After the STEP_OVER completes, the NotifyFramePop() is usually still in place. This keeps the thread in interp_only mode, which hurts performance. JVMTI has added a new ClearAllFramePops() API to allow clearing of the NotifyFramePop() and normal performance to resume.
