You’ll notice that in the list at the top of the functions that subprocess 
replaces, there are no os.exec* entries. subprocess is only for spawning new 
processes; if all you need to do is an exec, do an exec 
<http://docs.python.org/library/os.html#process-management>; subprocess 
can’t offer anything to make that any simpler.
