I believe this also includes the bitmap marking GC changes which will make the GC copy-on-write friendly. This is pretty important for a lot of folks running Ruby web servers.

See, for example:

This is probably the most exciting part to me: Having copy-on-write without having to run REE.

You can have this right now. We back ported the GC. Shopify in running on this ruby version in production.

Thats great! Hope this will work on 1.9.3p286 as well?

Yes, the Falcon patches work like a charm against p286.
