Issue #9518 has been updated by Masaya Tarui.

Sorry for such a late response.

I agree.

At the first time, I was introduled for reducing minor GC's long time
by rescan of huge size array.
But in real case, if there are huge size array, there may be other huge
data too.
No matter how it do, it have to take time.

a = [nil] * 131071
loop { a <<; a.pop }
# process RSS stays stable

a = [nil] * 131072
loop { a <<; a.pop }
# process RSS grows quickly and never falls

It seems to be related to this bit of code:
