The pprocess module uses pickles over sockets, mostly because the asynchronous aspects of the communication only appear to work reliably with sockets. See here for the code: http://www.python.org/pypi/pprocess Unlike your approach, pprocess employs the fork system call. In another project of mine - jailtools - I use some of the pprocess functionality with the subprocess module: http://www.python.org/pypi/jailtools I seem to recall that a few things are necessary when dealing with subprocesses, especially those which employ the python executable: running in unbuffered mode is one of those things.
