[RFC] Core: worker_processes <= NGX_MAX_PROCESSES

[Peter Stadler]

Would it be advisable to limit the number of worker_processes to 
NGX_MAX_PROCESSES at least when we have `worker_processes auto;` in the 
config?

A corresponding patch could be:

      if (ngx_strcmp(value[1].data, "auto") == 0) {
-        ccf->worker_processes = ngx_ncpu;
+        ccf->worker_processes = ngx_min(ngx_ncpu, NGX_MAX_PROCESSES);
          return NGX_CONF_OK;
      }
