I considered something like that but it seems to me like using an 
initialize_operation() function is adding to complexity, there is a 
function just to prepare values for the second function call. Also, if 
something like this were used I would prefer a function like 
get_some_control_block() that would also allocate memory for such a 
structure and return it.  I guess in my mind that just seems like it 
accomplishes more.

What do you think?
