// native work when a message loop is running nested or, in the case of Mac,
// in a different mode. Currently this is used for updating the HostZoomMap
// while the Wrench menu is open, allowing for the zoom display to update. See
// http://crbug.com/48679 for the full rationale.
//
// CAVEAT EMPTOR: This function's implementation is different across platforms
// and may run the Task in a way that differs from the stock MessageLoop. You
// should check the behavior on all platforms if you use this.
