(I presume that the * here means "insert your definition here").  This 
is exactly your problem, _assuming_ that you can get any realtime 
behaviour out of this call.  If you need that, use performance counters.

No, it's not balanced.  Most users would not like to go out of their way 
to make a broken implementation correct.  Most users are willing, 
however, to go out of their way to make something perform better if they 
need it.
