| See "man compat".  What you are seeing is the difference between ps(1) 
| output in "legacy" mode, attempting to duplicate the old, non-POSIX 
| behavior from 10.3 days, or "unix2003" mode.  Terminal login sessions 
| are normally automatically started with the COMMAND_MODE environment 
| variable set:
| 
| $ echo $COMMAND_MODE 
| unix2003
| 
| Adding an "env={"COMMAND_MODE": "unix2003"}" argument to your subprocess 
| Popen call should do the trick.

For an added datum, my machine (MacOSX 10.6.5 Intel Macbook Air) says
"legacy" instead of "unix2003".
