This pull request is to propose a minor change on how the scheduler works.
This PR should resolve #8 in which CPU utilization is high when running in QEMU.
This is a fix proposed in xv6-riscv as well (see mit-pdos/xv6-riscv#15) and is at least personally verified as lowering CPU utilization on my Macbook. I am not sure if there are any possible unintended side effects of this change, so additional testing and verification may be warranted.
