+// 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();
+// ...
+// }
