Hmmm, 'til then something along this should do it (warning: pseudo code, I
don't really know what I'm talking about when it comes to thread safety, 
one probably would have to do something with GMutex'es):

...
static guint menu_hyst_timeout_msecs;
...
void gtk_menu_hysteresis_timeout_set (guint timeout)
{
  lock_set (&menu_hyst_timeout_msecs);
  menu_hyst_timeout_msecs = timeout;
  lock_release (&menu_hyst_timeout_msecs);
}
...
giunt gtk_menu_hysteresis_timeout_get (void)
{
  guint timeout;
  lock_set (&menu_hyst_timeout_msecs);
  timeout = menu_hyst_timeout_msecs;
  lock_release (&menu_hyst_timeout_msecs);
  return timeout;
}
...
