I guess this issue and [ruby-talk:59662] concern with following
change.  GC only knows "big buffers" were allocated, but
doesn't know whether they're refered by live objects, so the
live memories amount would be estimated too small than the
allocated.

	* gc.c (gc_sweep): estimate how live objects consume memories.
