Swap helps in avoiding occasional problems. When I first started using
tmpfs I had 1.5 GB of RAM and 4GB of swap and set a limit 4GB (the
maximum for i386).
I currently have 16GB of RAM and a tmpfs limit of 25GB
I don't need that much, I never even come close to running out of
memory for port building. I just means that I don't have worry about

IIRC with 4 GiB RAM you can have up to 16 GiB of swap, so you could
support up to about 19 GiB of tmpfs if you want.
