Description:
During some heavy-load testing on a server, I saw the following;

| 39 | root | localhost:54479 | test | Query   |   -1 | NULL                            | show full processlist   

How to repeat:
SHOW FULL PROCESSLIST

not here (win7/64 bit server)

SELECT VERSION(); -- 5.5.7-rc 

SHOW FULL PROCESSLIST
/*
    Id  User    Host             db      Command    Time  State   Info                 
------  ------  ---------------  ------  -------  ------  ------  ---------------------
     1  root    localhost:54222  (NULL)  Query         0  (NULL)  show full processlist
     2  root    localhost:54223  (NULL)  Sleep         8          (NULL)               
 */

... but there is no 'heavy load' here!

changing this from verified to can't repeat.
there is no testcase, and haven't seen this myself (without setting timestamp) and/or changing clocks.
