Marin,

I believe you will find that Ada tasks can be modeled as Active Classes in
the current UML standard.  An Active Class is a class that has it's own
thread of control.  The notation on the diagram is augmented by making the
border around the class on the diagram bold.  All places where the class is
referenced will have the bold border to signify that the class is active.

Hope this helps,
