Bug Description

XtraDB provides the following info for the slow query log:
InnoDB_trx_id,
InnoDB_IO_r_ops,
InnoDB_IO_r_bytes,
InnoDB_IO_r_wait,
InnoDB_rec_lock_wait,
InnoDB_queue_wait,
InnoDB_pages_distinct.

Of these, only InnoDB_trx_id (and perhaps InnoDB_pages_distinct) could be considered tested. The I/O reads are not bumped in MTR because all the data is in the buffer pool, and the lock/queue waits are not even remotely tested.
