Original code was accessing rs_cache memory without holding a lock in some cases. If there was sufficient cache pressure, entry being accessed may be overwritten by another thread, resulting in a data race. We now make a thread local copy of the data, before releasing the lock. If we end up supporting UNW_CACHE_PER_THREAD properly in the future, this memcpy should be unnecessary.
