Correct me, if I am wrong, but my understanding has always been that the 
main program (or "environment task") can only terminate after all the 
tasks started within the main program have terminated (or, perhaps, have 
been aborted, or did run into an unhandled exception).

Once again, my understanding is that a main program with the "begin null; 
end Program_Name" does not terminate, as long as one of its tasks is still 
running. In fact, I am frequently using the "begin null; end 
Program_Name;" pattern myself, and "Program_Name" does not terminate, as 
long as any of its tasks is still alife and kicking.
