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
towards 0.5.

make sense?
