* gc.c: Tuning RincGC parameters.
Before this patch, gc_marks_step() marks (white -> grey) fixed
number objects. However, this strategy does not fit practical
cases, for example too slow to make progres.
This patch changes this strategy how many objects the
gc_marks_step() should handle.
We can estimate how many times gc_marks_step() is called during
this major marking (== C) with the free slot number in pooled
pages. We also can estimate the living object number (== L)
using last marked_slots value. We can solve this problem (how
many objects should be process in gc_marks_step()) by L/C.
* gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_sltos and
step_slots.
