// Similar to `AutoTimelineMarker`, but adds its traced marker to all docshells,
// not a single particular one. This is useful for operations that aren't
// associated with any one particular doc shell, or when it isn't clear which
// docshell triggered the operation.
//
// Example usage:
//
// {
// AutoGlobalTimelineMarker marker("Cycle Collection");
// nsCycleCollector* cc = GetCycleCollector();
// cc->Collect();
// ...
// }
