Heh, it worked a treat!
Blinkered as I was, I never thought to check the system temp dir;
df-ing our filesystem tells me that today there is only 174M free on
the root partition, where default /tmp is. That magical figure
explains why I was able to download a 170M file but not a 180M file.
Sorted.

Big big thanks,
