Log Message:
Make the clock interrupt tick based on absolute time instead of
relative time.  This prevents drifting.  Also, keep track of time
within userspace, so we do not have to make a syscall to get the
clock value.  This is approximately 7 times cheaper, but on the
negative side is limited to the clock interrupt frequency.
