So 4 GiBytyes of RAM is insufficient, even with use of: vm.pageout_oom_seq=120
Note: In this context increases is not going to help: it is way too little RAM
for pkg. (I was observing via top at the time.)
If pkg continues to require such RAM+SWAP usage, FreeBSD is going to end up
requiring more than, say, 5 GiBytes of RAM+SWAP, even for UFS contexts.

For reference, see:

with details of my test context (where swap was in use).
Interesting.
Here, with faster storage for a new guest, 1,024 MB base memory was
enough – for both UFS and ZFS – as outlined below.

The same with ZFS. Success with, then without, the
increased vm.pageout_oom_seq
