Nah, I get that too.  I think it's an IDLE thing.

>From the command line:

Python 2.4.3 (#1, Mar 30 2006, 11:02:16)
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> raise SystemExit

IDLE 1.1.3

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in -toplevel-
    raise SystemExit
SystemExit

IDLE will just be catching the exception, I guess.  You can do it yourself:

>>> try:
...  sys.exit()
... except SystemExit:
...  print 'Not exiting!'
...
Not exiting!
