>Description:

ADD INDEX for a modest-sized table hangs. The temporary table gets
created, but then the process forever hangs on 

lwp_cond_wait(0xFF345548, 0xFF345558, 0xFF33EDB0) Err#62 ETIME

according to truss. There are no other processes active, says SHOW
PROCESSLIST. The table (myISAM) has lots of indices, including a
full-text index.

>How-To-Repeat:

alter table add index (number(4))

>Fix:
