<div>Now, I was able to follow the "send" path thoroughly, but I am stuck in the "receive" path: I went from the io.c:driver_output to dist.c:erts_net_message to erl_message.c:erts_queue_dist_message, and at this point the received message is put inside the process queue.</div>
<div>Where is the message extracted then? I guess that somewhere the message is taken from the queue, the binary stream (the message, because the header is already extracted in dist.c) unpacked into a term and the term given to the process, and in particular I am looking for the place where the term is unpacked...</div>
