I tried subprocess.call('calc.exec'): it works.
I tried p=subprocess.Popen('echo hello', shell=True, stdout=subprocess.PIPE);
p.communicate(): it works too (I get the output and there is no MS-DOS popup).

platform.popen() and os.popen() have the same requirement: call process.wait()
on file.close(). os.popen() does already implement that using _wrap_close. I
don't want to copy/paste the code from os. os.popen() does still exist, why not
reusing it?
Anyway, if we remove os.popen(), we should remove platform.popen() too. But I
don't want/plan to remove os.popen().
