Possible change would be to use gcpause to trigger small gc,
and 100+gcpause to trigger full gc. I.e.

    if (g->totalbytes > g->lastmajormem/100 * (100 + g->gcpause))
      g->lastmajormem = 0;  /* signal for a major collection */

This would keep the meaning more or less consistent in both modes and
avoid the pathological case with fullgc when gcpause < 100.

I tried and it seems to work well.
