The idle module implements idle detection in Core. Idle detection attempts to solve the problem of when Core is "sufficiently idle" for a testcase to proceed to the next action. (In particular, testcases often want to know when the consequences of a click on a page are "finished").
The idle detection works by placing probe-like objects around in code which performs central tasks, like paint and reflow. These objects report to a manager when their related activity beings and ends, and the manager in turn reports to a set of listeners when we move from an idle state with no live activities, to a busy state (and vice-versa).
Components interested in knowing when we are idle (or when we leave an
idle state) must implement the OpActivityListener interface, and
subscribe for the events using OpIdleDetector::AddListener. The
OpIdleDetector singleton is globally available under the alias
g_idle_detector.
