 // Manages per-tab state with regard to hung plugins. This only handles
 // Pepper plugins which we know are windowless. Hung NPAPI plugins (which
 // may have native windows) can not be handled with infobars and have a
 // separate OS-specific hang monitoring.
 //
 // Our job is:
 // - Pop up an infobar when a plugin is hung.
 // - Terminate the plugin process if the user so chooses.
 // - Periodically re-show the hung plugin infobar if the user closes it without
 //   terminating the plugin.
 // - Hide the infobar if the plugin starts responding again.
 // - Keep track of all of this for any number of plugins.
