Thanks for your help. I decided to go the Win32 way. Here's my solution...

---
PROCESS_STILL_RUNNING = 259
def run_script(test_dir, timeout = 2):
    timeout = timeout * 60 # Convert the timeout param from minutes to
seconds
    os.chdir(test_dir)
    pinfo = win32process.CreateProcess(
        None, 'python.exe "' + test_dir + '\\test.py"', None, None, 0, 0,
        None, None, win32process.STARTUPINFO())

    retval = PROCESS_STILL_RUNNING
    while retval == PROCESS_STILL_RUNNING:
        time.sleep(0.25)
        timeout = timeout - 0.25
        if timeout <= 0:
            win32process.TerminateProcess(pinfo[0], 1)
            print "ERROR: Process timeout"
            break
        retval = win32process.GetExitCodeProcess(pinfo[0])
    os.chdir("..\\")
    return retval
