OK, there's something going on here:
$ set | grep IFS
IFS=$' \t\n'
$ python
Python 2.4.1 (#2, May  5 2005, 11:32:06)
[GCC 3.3.5 (Debian 1:3.3.5-12)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> f = subprocess.Popen("set | grep IFS", shell=True, stdout=subprocess.PIPE)
>>> f.stdout.readlines()
["IFS=' \t\n"]
>>>

(Hmph, I don't have any other non-Windows boxes with >=2.4 to hand.)
