What is the (hopefully unique) obvious way of runnign a sub-process if I
want to get the exit code and input without resorting to multi-threading?

It seems like I should be able to do the following:

foo = popen2.Popen3(cmd)
foo.wait()
foo.fromchild.read()
I do it like this:

def shell_command(cmd):
# There mustnot be output to stdout or stderr
# otherwise an exception is raised

p=popen2.Popen4(cmd) # read stdout and stderr
output=p.fromchild.read()
ret=p.wait()
if ret or output:
raise("Error in shell_command '%s': ret=%s output='%s'" %(
cmd, ret, output))
