+ * and passes an nsIHangReport for the subject parameter. There is at most one
+ * nsIHangReport associated with a given content process. As long as the content
+ * process stays stuck, the "process-hang-report" observer will continue to be
+ * notified at regular intervals (approximately once per second). The content
+ * process will continue to run uninhibitedly during this time.
