need help to join mysql query..(pure mysql query)

hi,
bellow statement will give output like this

mysql> SELECT THREAD_ID, EVENT_ID, EVENT_NAME, SOURCE, TIMER_START, OBJECT_INSTANCE_BEGIN, OPERATION FROM EVENTS_WAITS_CURRENT WHERE THREAD_ID IN(SELECT LOCKED_BY_THREAD_ID FROM MUTEX_INSTANCES WHERE LOCKED_BY_THREAD_ID IS NOT NULL)\G
*************************** 1. row ***************************
            THREAD_ID: 126
             EVENT_ID: 605760540
           EVENT_NAME: wait/io/file/innodb/innodb_data_file
               SOURCE: fil0fil.c:4509
          TIMER_START: 5985772299618636
OBJECT_INSTANCE_BEGIN: 139829830175456
            OPERATION: write
1 row in set (0.44 sec)


now if i run another query ..

 desc threads;
+----------------+--------------+------+-----+---------+-------+
| Field          | Type         | Null | Key | Default | Extra |
+----------------+--------------+------+-----+---------+-------+
| THREAD_ID      | int(11)      | NO   |     | NULL    |       |
| PROCESSLIST_ID | int(11)      | YES  |     | NULL    |       |
| NAME           | varchar(128) | NO   |     | NULL    |       |
+----------------+--------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

mysql> select processlist_id from threads where thread_id=126
    -> ;
+----------------+
| processlist_id |
+----------------+
|            109 |
+----------------+
1 row in set (0.00 sec)


now what i want is :
insteads of run 2 different query, how can i  add  2nd select statement in to first statement so that it add process_list in to the first query's output l.. . so when i execute first query , the output will be :

*************************** 1. row ***************************
            THREAD_ID: 126
             EVENT_ID: 605760540
              processlist_id:109
           EVENT_NAME: wait/io/file/innodb/innodb_data_file
               SOURCE: fil0fil.c:4509
          TIMER_START: 5985772299618636
OBJECT_INSTANCE_BEGIN: 139829830175456
            OPERATION: write
