- * ThreadStackHelper is used to retrieve the profiler pseudo-stack of a
- * thread, as an alternative of using the profiler to take a profile.

- * then another thread can call ThreadStackHelper::GetStack to retrieve
- * the pseudo-stack of the target thread at that instant.
- *
- * Only non-copying labels are included in the stack, which means labels
- * with custom text and markers are not included.
