I thought that I had fixed that for internal temporary files but
apparently I haven't done that.

I will create a Jira task for doing that for Aria (which is used for
internal temporary tables in MariaDB).

Explicit temporary tables are a bit hard as this depends on the
storage engine.

I am not sure how InnoDB reacts to a disk full for a temporary table.
Jan, do you happen to know?
At least, it should not wait for disk space to be freed, like MyISAM
or Aria.
