Summary: popen4 fails if cmd is unicode.

Initial Comment:
In popen2.py there is a class Popen3. It contains
a method _run_child().

-------
def _run_child(self, cmd):
    if type(cmd) == type(''):
        cmd = ['/bin/sh', '-c', cmd]
-------

I think that this test is attempting to find if the
"cmd" is not a list. Unfortunately <type 'unicode'>
does not get turned into a list. A better test may
be:

-----
def _run_child(self, cmd):
    if repr(type(cmd)) != "<type 'list'>"
        cmd = ['/bin/sh', '-c', cmd] 
-----

This problem shows up when creating commands from XML
files read by "xml.sax". Beta 2.2b1 still has this
code.
