should raise an AttributeError as the int returned by subprocess.call 
does not have a .communicate method.

Why do you think that? All function calls block until the function 
returns, at which point blocking ceases.  If you call 
Popen(someprog).communicate() and someprog runs quickly, you will hardly 
notice the blocking time.
