Fixed bug in lock tables introduced by shared locks.

mysql> select INET_ATON("209.207.224.40");

       ->  3520061480

@end example

The generated number is always in network byte order; For example the

above number is calculated as @code{209*255^3 + 207*255^2 + 224*255 +40}.

@findex MASTER_POS_WAIT()

@item MASTER_POS_WAIT(log_name, log_pos)

Blocks until the slave reaches the specified position in the master log during

dummy1	count(distinct id)

NULL	1
