+Directory /tmp is now on tmpfs, which can cause problems with limitted space
+or replication. It's documented here:
+http://dev.mysql.com/doc/refman/5.5/en/server-options.html#option_mysqld_tmpdir
+
+"If the MySQL server is acting as a replication slave, you should not set --tmpdir
+to point to a directory on a memory-based file system or to a directory that is
+cleared when the server host restarts."
