mysql engine typically uses memory for temporary tables, but column `bug` id `text` type so mysql use myisam on disk.


Check this:
- http://dev.mysql.com/doc/refman/5.1/en/memory-storage-engine.html

"MEMORY tables cannot contain BLOB or TEXT columns" -


- http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_max_heap_table_size

- http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tmp_table_size

re-mount mysql tmpdir to tmpfs in RAM :-)
