As I pointed out in very first followup (and no one corrected me to say
I was wrong), my understanding is that the Apache SetEnv directory
merely sets an entry in a table object which is then used to populate
the environment of CGI scripts when run. That is, SetEnv doesn't actually
change the environment of Apache itself, thus mod_python wouldn't see
any values set by SetEnv in sys.environ.

  http://httpd.apache.org/docs/2.0/mod/mod_env.html#setenv

Code from httpd which is triggered by SetEnv is:

static const char *add_env_module_vars_set(cmd_parms *cmd, void *sconf_,
                                           const char *name, const char *value)
{
    env_dir_config_rec *sconf = sconf_;

    /* name is mandatory, value is optional.  no value means
     * set the variable to an empty string
     */
    apr_table_setn(sconf->vars, name, value ? value : "");

    return NULL;
}

In other words, doesn't call putenv() so can't be used to set PYTHONHOME or
PYTHONPATH.
