ACK 0d8433ddac1c74c71a1212ff15aa1eef283524a2

FWIW this issue exists on more operating systems (at least OpenBSD I think?), and it may be good to have a more general mention in the documentation on the hefty temp-space requirements and how to override the temporary directory if it's not possible to resize the OS-given one. That said, this is an improvemeent.

This should only be an issue for functional tests? It is also possible to overwrite the temp dir (instead of increasing its size, which might not always be possible)

(The default is default=tempfile.gettempdir() for the python tests)

I would think if you don't have enough RAM, we ought to move it to non-RAM storage?

Sure, I didn't see the temp file could be modified...
