When receiving data from the network, and deserializing them into packets, MessagePack creates a new instance.

If we could reuse packets and write new data into them, that would solve the problem.
This PR #110 could fix it, but I'm not sure what its status is. Is it done? Or still in the prototyping stage?

How does everyone avoid needless allocations when deserializing?
Is it just accepted? What about lag from garbage collection?
