**	each recipient is worth WkRecipFact priority points.  Each time
**	we reprocess a message the priority is adjusted by WkTimeFact.
**	WkTimeFact should normally decrease the priority so that jobs
**	that have historically failed will be run later; thanks go to
**	Jay Lepreau at Utah for pointing out the error in my thinking.
