Packets are referenced counted, so once you give it to enet_peer_send() 
that increments its reference count by 1. It deletes when reference 
count hits zero. Reference counts are decremented when the packet is 
actually sent and no longer needed on that peer.

enet_packet_create() makes a copy of the data unless you use 
ENET_PACKET_FLAG_NO_ALLOCATE, in which case there is no copy. 
enet_peer_send() never copies anything, though, which was the claim.
