It's does nothing but to send the received Packet to a process which is
intended to do the actual handling, then it immediately returns to
receiving packets.

For the next sessions we're most likely to look into {active, true}
further, testing different buffer sizes et al with it to see how it behaves.

Should {active, true} prove to be the fastest way of doing planned
things, we'll implement some different means of preventing a system
lock-up :)
