New submission from Christoph Neuroth <christoph.neur...@googlemail.com>:

Currently, the documentation of subprocess only says "Calling the program 
through the shell is usually not required.". IMHO there should be a real 
warning (like, in its own box with a couple of big exclamation marks ;)) about 
the security implications of using this and detailed instructions of how to 
avoid it. People tend to use this functionality just because they "know how to 
use the shell" and its just so convenient - and by doing so they create huge 
security holes in their applications.
