Reverted for now because of regressions in:
bm_array_sample_100k__6k
bm_array_sample_100k___10k
bm_array_sample_100k___50k
I think the original unsigned + underflow avoidance code
prevented us from accounting free() properly, and we were
triggering GC more as a result.
With this patch, frees are accounted properly so malloc_increase
grew too slowly...
Also, I think it would be beneficial to check malloc_increase
and do a lazy sweep step BEFORE calling malloc, since that should
improve cache locality in malloc (because they're usually LIFO).
