If one uses subprocess.Popen(args, ..., shell=True, ...)
When args finishes execution, does the shell terminate? Either way
seems problematic.
If it does not terminate, then it seems as if calls like wait and
communicate would never return. It also seems the subprocess would
never die, and that most of the examples with the shell True would leave
processes lying around.
No, p.wait() will immediately return, and p.communicate() discards
everything new coming.
If it does terminate, then how can you stuff new commands down the pipe
to the subprocesses stdin?
start a new shell, of course.
Does this module contemplate receiving multiple commands for the shell
to execute?
yes, use several subprocess.Popen() or call a batch/shell script.
