Very probably.

Well, the documentation tells you the difference between LIST-ITEM-LOCKS 
and SHOW-ITEM-LOCKS already :-)

You mean: The locking information shown by LIST-ITEM-LOCKS can be 
collected relatively quickly, but the extra information that 
SHOW-ITEM-LOCKS collects may be gathered more efficiently if the locking 
mechanism in use on your system allows it to be so, which it does not 
always do.

I am sure that the algorithm can be improved too, but the basic idea is 
that you:

1) Fix your application issue;
2-99) See 1;
100) First use LIST-ITEM-LOCKS
101) If you cannot work out what is going on in LIST-ITEM-LOCKS, use 
SHOW-ITEM-LOCKS
102) If you cannot work it out now, then become a systems analyst and 
leave it to the programmers ;-)

The reason there are two commands is historic.

SHOW-ITEM-LOCKS can be improved I am sure, but where do you want TEMENOS 
to spend their efforts? :-)
