Documented where? Neither the on-line documentation nor the function
docstring mentions anything about it that I can see:

http://docs.python.org/py3k/library/os.html#os.system

>>> help(os.system)
Help on built-in function system in module posix:

system(...)
    system(command) -> exit_status

    Execute the command (a string) in a subshell.
