Hi Dominik, It should be fine, though I don't think it's been tested in a multi-threaded environment. It's single writer, multiple-reader, and each piece of state has only a single modifier. It's basically a variant on the standard lock-free ring buffer. On non-x86 machine SMP machines (e.g. PPC) it may require the addition of memory barriers.
