Thank you for the paper, and for the work!

Can I ask a newbish question: will this new GC be available on all OS:s and CPU architectures, or only on some? I don't see anything in the paper about being limiting to some certain platform, so my hopes are high :).

It should be pretty portable, porting is just a matter of time and interest. The main thing is that the compiler needs to use a (more precise, lower overhead) software write barrier rather than using the (coarser, slower) hardware write barrier which was around the longest. I also have to wonder how well the bit-scanning algorithms fare on big-endian, or is that taking "all CPU architectures" too far?
