I've use a amd64 system with 192 GiBytes of RAM and 512 GiBytes of
SWAP, so 704 GiBytes of RAM+SWAP. 32 FreeBSD cpus. USE_TMPFS=all
with a TMPFS_BLACKLIST . (The other builders that I have access to
have less resources.)

When graphics/sdl2_gpu is built with USE_TMPFS=all on this system,
this system runs out of RAM+SWAP and suffers OOM kills or related
panics. This is during doxygen activity and its use of multiple
dot processes, which are what leads to the RAM+SWAP use:

I may end up overriding the:

DOCS_ALL_TARGET= doc


I looked at an example log from an official server and it suggests
problems as well my logs doing so, such as:

Warning: Unable to reclaim box space in spline routing for edge "Node12" -> 
"Node11". Something is probably seriously wrong.

I've no way to know if the likes of beefy18 is getting OOM kills
or the like or how much RAM+SWAP such machiens ahve. But I do
get the OOM kills.
