[mod_python] Importing modules in a new process.

I have been having this problem for a while, but it has just recently gotten
to be enough of a bother that I thought I should figure out what's going on.
I have a simple application (myapp.py) as follows:


import my_module

import datetime

import sys


print "Hello World."


Which (of course) runs fine from the interpreter.  The problem is when I
start that application with the subprocess module via a separate application
through mod_python and a web request (initiate.py) as follows:


import subprocess


subprocess.Popen(['python myapp.py', shell=True)


When myapp.py is initiated through the Popen, it is unable to locate the
my_module module and fails.  When 'import my_module' is removed the
application completes fine, which leads me to believe it is a problem with
the my_module module.  Since I am able to run myapp.py fine from the
interpreter rather than remotely, I was assuming that there was a
permissions problem with the module.  Unfortunately, it still gave me the
same err with 777 permissions.  


Can anyone suggest where to go from here, please?
