This is interesting.

I tested on cacti database and on 2 Joomla databases with same results. 
But there might be something there.

Database changed
mysql> CREATE TEMPORARY TABLE IF NOT EXISTS plugin_temp_table LIKE jos_menu;
ERROR 1004 (HY000): Can't create file '/tmp/#sql21f8_f3_1.frm' (errno: 9)
mysql> CREATE TEMPORARY TABLE barney (SELECT * FROM jos_menu WHERE 1=0);
Query OK, 0 rows affected (0.01 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> CREATE TEMPORARY TABLE IF NOT EXISTS plugintest LIKE jos_menu;
ERROR 1004 (HY000): Can't create file '/tmp/#sql21f8_f3_3.frm' (errno: 9)
mysql> CREATE TEMPORARY TABLE IF NOT EXISTS barney LIKE jos_menu;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Changed name of table to create produced result, but with warning.
