The full message was "swap zone exhausted, increase kern.maxswzone" - I
guess that actual swap wasn't exhausted, but just space for metadata. So
in tmpfs' defense,  AMD64 boots with a kern.maxswzone of 32MB like i386,
which only allows ~7 GB of swap to be allocated.

I'll see if I can get the machine to wedge again, then increase
kern.maxswzone, and repeat.
