It was a generational gc, I described earlier how it used page faults instead of write barriers. I eventually removed the page fault system because it was faster without it.
Page faults are inferrior to compiler generated write barriers. Because with a page fault startegy you pay for every write. Even if the write does not write a pointer. Compiler generated write barriers only apply to pointers written through another pointer.
