> Fix For: 2.3.0

>
> The current way to recognize the handler's thread is using heavyweight
> operations (allocations + atomic set/get) that limit some compiler
> optimizations on the (core) packet handling path.
> The same logic can be achieved using only a ThreadLocal map and a cached
> marker instance.
