Re: Best way to get to CAS/fetch-and-add on unboxed vectors?

[@Aleksey] Very good point! I'd missed that vector does the SOA->AOS business too. (I thought that was just Repa & Accelerate.) In any case, an unboxed vector of tuples can't *actually* support atomic CAS anyway, so not supporting it is inevitable. It does mean that exposeMutableByteArray can't be a method of the Unbox class. It would need to be another class capturing the subset of vector types that are "Atomic" (support concurrent/atomic memory ops).
