Correct.  I had a module that listed 7 calls to it.  I had to check why 
and found out that a user program had 6 links into the module.  Don't 
know why, but it looks like poor programming practices and that the 
first call to use the module was not released like it should be, by the 
programmer and not by a clean up routine.
