/**
* When a content process hangs, Gecko notifies "process-hang-report" observers
* 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.
