Interface-wise, writing 1 to idle file is fine. This does move away
the interface from being a purely semantical weight tree, which is a
concern and I have a difficult time seeing that the stated benefits
are significant enough to justify the changes. That said, this is
primarily a scheduler decision, so if you think the addition is
justified, please go ahead.
