I'm unsure about this. I _hate_ the extra branches this adds;

[ruby-core:61175] [ruby-trunk - Bug #9584] RGenGC regression in CoW sharing

Yes, but look again at the SHARED_* numbers from nari's test code. #define USE_RGENGC 0 shares more memory. > And also, I'm worry about WB performance. I doubt it's much difference. I haven't been able to fix my bitmap patch to test performance (can't finish build, even). I suspect it's fake objects, I marked some with FL_PERMANENT but maybe I missed some.
