* It looks like this has been like that since day-1 (i.e for as long
as we have history for it.
* That function seems to be only used for display purpose at only place only.
* It looks like there should be break after each case and no
fall-through. I don't see the reason why one would want to obfuscate
the true value of priority in a trace message.
