Clare,

I disagree re setting the activitiy level. Setting it to a low value makes
likely the condition where jobs are ineligible even though there are cpu
resources available to run the job. The job mix changes during the day, week
to week, etc. Forcing the activity level to a set value ignores these
fluctuations.

My solution is to set the interactive activity level high and the timeslice
very low.
