I don't know the minimum, but:
* I've been using 2G tmpfs for some time without issue.
* The above error messages may be misleading: it is *possible* that
  the actual complaint is not lack of space, but lack of available
  inodes -- you can't tell from the message alone.  "df -i /tmp" is
  likely to be helpful in diagosing what is actually the problem.
