My apologies if I've misunderstood something, but why does this of any
concern?  Machine has 64GB RAM.  You have a single swap slice that's
effectively 32GB.  How is a kernel panic worth of 64GB RAM going to fit
into a 32GB swap slice?

I think what folks are saying is that if you use multiple swap slices
(e.g. two of 32GB each), you can achieve what you need.
