The responder name is now cached in LLURLRequest (ResponderBase::getName() must return a string literal). The run time (in the main thread) per state machine is now accumulated in AIStateMachine (instead of AIEngine::QueueElement). When AIStateMachine::mainloop runs longer than StateMachineMaxTime then a warning is printed that now includes the time spent in the slowest state machine (that frame) and (if it is a LLURLRequest) what the corresponding responder is. Also the total accumulated run time of that state machine is printed. From this is can be concluded that the only responder currently regularly holding up the main thread is LLMeshLODResponder (mostly 30 to 100 ms, but with spikes in the 1 to 2 second range some times).
