Currently G1 only uses pause times as a metric to calculate the gc cpu usage.
This disregards concurrent cpu usage completely.
Make the calculation more accurate; this might require retuning of `GCTimeRatio`.
Some platforms may not support more exact CPU measurements so the current mechanism might need to be kept.
