it would mean that a user's past usage becomes less important for
their current fair-share of resources. it's just a knob to control
how long their past usage should count against their current priority.
if you don't care about past usage at all, you could set the halflife
to 1 second. the end result would be that users' priorities would
very closely follow their current resource usage, and as soon as they
stopped running jobs, their priority would immediately fall back
