agreed. swap has never worked. The kernel was and still has been higher
in priority.

I show and it has never shown otherwise):
dene# pstat -s
Device 1K-blocks Used Avail Capacity Type
/dev/rz0b 65536 4 65532 0% Interleaved
but perhaps pstat -T is more telling:
dene# pstat -T
77/2588 files
8095 vnodes
0M/64M swap space
I just did a 4K dd of the swap partition to see what's in there.
Not much. I was hoping to find some indication of structure, but it's
all uniformly 0x6C throughout:
