    If I call a burst method "void add (ref float3 a, ref float3 b)" like "add(ref someclass.varA, ref someother.varB)", is that potentially unsafe? What if a GC occurs (from another thread allocating or such) while the burst function is called? Does it pin the object, or does it use a temp copy, or some other way?

    Yes, it should be safe as the .NET runtime is making sure that these refs are "fixed"
