Why? 

Running IDLE from the command-line is IMHO more interesting, both with:

$ idle3.3   # located in /Library/Framework/Python.framework/Versions/3.3/bin

and

$ "/Applications/Python 3.3/IDLE.app/Contents/MacOS/IDLE"

The first command starts IDLE the same way as on other platforms, the latter
is the command used to start IDLE from the OSX GUI.

Another command to try:

$ python3.3 -c 'import idlelib.run; idlelib.run.main()' 900

That is basicly how IDLE starts its subprocess (900 is a random port number). This
should print that IDLE cannot cannot connect to the main proces, on my machine followed
by a hard hang that requires a force quit because the child process tries to use Tk
from a thread that isn't the main thread:

IDLE Subprocess: socket error: Connection refused, retrying....
IDLE Subprocess: socket error: Connection refused, retrying....
IDLE Subprocess: socket error: Connection refused, retrying....
IDLE Subprocess: Connection to IDLE GUI failed, exiting.
2013-08-23 07:49:04.670 Python[3793:1803] NSAlert is being used from a background thread, which is not safe.  This is probably going to crash sometimes. Break on void _NSAlertWarnUnsafeBackgroundThreadUsage() to debug.  This will be logged only once.  This may break in the future.

(The last line is acompanied by a small white empty window)
