With the modified stepmul logic and this fix -- great.
Do you think the modified stepmul logic is needed, with the fix?
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.
