Although it is an old question, it has a high google rank. so I decided to post an answer with the new method someone can use in python 3 to manage this easily and with confidence. as of python 3.5 you there is a new method added to subprocess package called run().

As the documentation says:

It is the recommended approach to invoking sub processes for all use cases it can handle. For more advanced use cases, the underlying Popen interface can be used directly.

The subprocess.run():

Runs a command described by args. Wait for the command to complete, then return a CompletedProcess instance.

for example one can run this snippet within a python console:

>>> subprocess.run(["ls", "-l"])  # doesn't capture output
CompletedProcess(args=['ls', '-l'], returncode=0)

P.S. In case of the OP's specific question, I wasn't able to reproduce his problem. commands I run with popen() are terminating properly.
