 I think this is an unrelated bug in tmpfs related to how the
 libreoffice build writes files. If you look in df -h output it will
 say /tmp is out of space, but du -h says the libreoffice work directory
 only takes 25GB. Deleting the work directory reclaims all the space so
 tmpfs files seem to leak memory for the duration of their existence.
