As to why the hook in `os::physical_memory()` isn't sufficient I'm at a loss. The original review here https://mail.openjdk.org/pipermail/hotspot-dev/2017-October/028635.html suggests that there was supposed to be some support for interleaving os initialization and arguments processing, but I don't see it. To be safe, I'd just leave this as it is for this patch and potentially clean this up as a separate bug. Thoughts?

Okay. Maybe something for a follow-up RFE.
