As for your comments on how user code is calling JobTracker.getTracker() function meaningfully, here is one case.
I am trying to have a "monitoring" module that periodically checks for any failed jobs and alert users if there are any. To do so, I need to have an instance of JobTracker, since it contains all the info about the job status. I may add my "monitoring" code into JobTracker, but I don't think it's a very elegant solution. If JobTracker.getTracker() method were to be taken out eventually, is there any other way of getting job status info?
