If the clock_time never advances beyond zero, it definitely looks like
some problem with fluid_curtime (or g_get_current_time in glib).

Could it be a rounding problem? Please try this change to fluid_curtime():

unsigned int fluid_curtime(void)
{
  GTimeVal timeval;
  unsigned int result;

  g_get_current_time (&timeval);
  result = (unsigned int) (timeval.tv_sec * (gdouble) 1000.0 +
timeval.tv_usec / (gdouble) 1000.0);
  fprintf(stderr, "tv_sec = %d, tv_usec = %d, curtime = %d\n",
timeval.tv_sec, timeval.tv_usec, result);
  return result;
}
