If your shared pool is split to several separate areas protected by  separate 
shared pool child latches, then every shared pool area has  its own LRU lists, 
thus x$kghlu reports a row for each of them. 

Multiple shared pool areas feature is available from 9i - _kghdsidx_count 
parameter controls how many shared pool areas/child latches are used (max is 7).

Also, if java pool is defined, x$kghlu reports one additional row in 10g, maybe 
in 9i as well, I haven't checked (probably because java pool memory is managed 
by the same KGH module which handles shared pool).
