Review Comment:
Ah. So this was explicitly done for our internal build since we run ZGC only
on this release and the logging volume was roughly doubled w/the switch to ZGC.
Let me take a todo item to break out that threshold to offer a different value
we rely on in the ZGC case instead of hijacking the default shared value, thus
polluting the G1 / CMS cases.
