No message. Too fast.

Hi Helder,
I can add a data point, if it's useful to know... on my Windows 7 64-bit, I have
Python 3 running, and this all works fine with the Python 3 tweak to test.py:
-----
import struct
print("n-bits=", struct.calcsize("P") * 8)
-----
IDL> spawn, 'python test.py', out, err
IDL> out,err
n-bits= 64
IDL> random=pyimport("random")

Bonus section:
In case you are tempted to jump to Python 3, here's how I did it, using
Miniconda3 and Anaconda. My recipe for getting Python 3.3 (I'm using Windows 7
64-bit, IDL 8.3 64-bit):
On http://continuum.io/blog/anaconda-python-3 , follow instructions for
Installing Miniconda3:
Go to this page:
http://repo.continuum.io/miniconda/index.html
Download the latest Miniconda3 for your OS, install it, then at a Command Prompt:
C:\> conda install anaconda
It will list the hundreds of things it will download and link, then tell it to
Proceed (type "y" then Enter)
Be patient! Then, at the command prompt, you should be able to start a Python
session and import numpy and scipy:
C:\>python
Python 3.3.4 |Anaconda 1.9.1 (64-bit)| (default, Feb 10 2014, 17:54:43) [MSC v.1
600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> import scipy as sp
>>> exit()
Test IDL and Slither (installed with correct DLM for Python 3.3):
IDL> DLM_LOAD('Slither')

Both are running IDL 8.2 and Python 2.7 (Specifically, the Python(x,y) installation). In both cases, attempting to call pyimport() to import any python module crashes IDL. It happens pretty quickly, so i feel like it's something simple, but not sure.
