   It is crucial to note that while you can adjust a cost downwards,
   adjusting it upwards doesn't work.  So if you have an exception
   where a cost is higher, you have to set the default cost to the
   higher value, and use ADJUST_COST to lower it in the
   non-exceptional case.

Or just use the MD_SCHED_* facilties and avoid all of these issues :-)
