On OSX you can also use GCD.  But kqueue is not integrated into the event loop either, so it would require additional code anyway.  Possibly by dispatching another thread.  I guess this is required for any BSD system.

AFAIK, using Glib and NS just means calling xg_select instead of pselect in one place.  It is not done, because there has been no need for it.  GLib and DBus is not much used for native OSX apps (if at all).  GNUStep would be another matter.
