I got greedy! :) i also wanted to embed my newfound understanding of
gpart, geom, and swapping into the noggin so I could move on.

So far, it works, but there haven't been enough changes in the ports
tree that synth even needs a cuppa.
I think what I am going to do is to wipe the machine one more time
from 12.1R (with 16G swap, as both you and Peter suggest), STABLE-ize
it, and see if synth can handle the entire installed ports tree
(around 300 primary+dependency ports) without crashing and with
conservative builder-subtask limits. It will take it three days to do
that, but I think I know enough of the gotchas to get it to succeed.
It's a good idea to have a second one in reserve, but when it broke
through the roof it happened way too fast for me to actually enable
anything. I'll see if I can make a one-character script invocation and
try it, though!
