- * For versions of these calls that take additoinal args and value pairs we currently just drop them
- * and report only the name. Since ATrace is a simple push and pop system (all traces are fully
- * nested), if using BEGIN and END you should also make sure your calls are properly nested (i.e. if
- * startA is before startB, then endB is before endA).
