Thank you Thomas for chiming in.

Thomas mentioned using `Safefetch` in his pre-review of https://github.com/openjdk/jdk/pull/8571 but I thought it would be better to leave that for a follow-up as there are a few issues of interest here.

I understand that this fix doesn't solve everything, but it's a step in the right direction.

There will most certainly be more work in this area.
