Thanks Jachym,

spawn invokes gen_server when NodeName =/= node(), which invokes
gen:call, which invokes erlang:send.

But I was unable to find who exports erlang:send... the erlang module
(erlang.erl) only exports dsend, which connnects+invokes send.

Reading the net_kernel and do_connect implementations, it seems as
connections are treated with their own local pids and kept alive. But

Any suggestions where to find the send implementation?
