ataly: I've been trying to insert TRACE_EVENT_STATE() macros into all DOM getters/setters/methods (https://bugs.webkit.org/show_bug.cgi?id=110667). Given that each DOM getter/setter/method takes within ~20 nano seconds, we cannot log something at every call. So TRACE_EVENT_STATE() just updates a global state variable so that a sampling profiler can read the global state periodically. The traced results will be integrated to about://tracing.
