The aim is to have more flex space for the kernel on machines with more
resources. Although the dump will be collected pretty fast and the memory
released really early on allowing the machine to have the full memory
available, this alleviates any issues that can be caused by having way too
little memory on very very large systems during those few minutes.

I think this would be an issue for distro kernels that have minimum
requirements for memory above 256MB. It seems like a reasonable attempt
to have good defaults. The user can always override it with boot args.
I'm not sure where the exact numbers should be but the general statement
that larger memory systems should have more memory to boot with seems
like a good one.
