why nginx clear environment when init process?

[Ken]

in

static void
ngx_procs_process_init(ngx_cycle_t *cycle, ngx_proc_module_t *module,
    ngx_int_t priority)
{
  .....

    if (*ngx_set_environment(cycle, NULL)* == NULL) {
        /* fatal */
        exit(2);
    }

.....

why doing this? it make impossible to getenv in worker process.
