In XMLHttpRequest this is certainly accurate. You will never see .responseText changing in the middle of an execution thread, it's always changed in response of a task run from the event loop. This task can (and IMO should) synchronously fire the 'progress' event (within the usual limitations of never firing that event more often than every 50ms). / Jonas
