glib's main loop integration in Emacs is implemented by xg_select, a
replacement for pselect in case glib is linked to Emacs. However, in
file process.c:4915, we have the code

--8<---------------cut here---------------start------------->8---
#if defined (HAVE_NS)
          nfds = ns_select
#elif defined (HAVE_GLIB)
          nfds = xg_select
#else
          nfds = pselect
#endif
            (max (max_process_desc, max_input_desc) + 1,
             &Available,
             (check_write ? &Writeok : 0),
             NULL, &timeout, NULL);
--8<---------------cut here---------------end--------------->8---

That means, that in your case on OS X ns_select is called, instead of
xg_select.

I have no idea how to solve this properly.
