Erlang processes are lightweight (grow and shrink dynamically) with small memory footprint, fast to create and terminate, and the scheduling overhead is low. 12.2 Process Creation. A process is created by calling spawn: For this reason, Erlang provides the special atom kill as a reason for an exit signal. An exit signal containing the reason kill cannot be trapped; thus the exit signal is unstoppable. Unconditionally terminating the entire network is however something dangerous, so when a process terminates because of an incoming kill exit signal it will send to its linked processes a killed exit signal Erlang Exit Signals Tests in Elixir, Inspired by http://j.mp/1T2KATV - viralelixir/erlex_exit_signals OtpErlangExit public OtpErlangExit(java.lang.String reason, OtpErlangPid pid). Equivalent to OtpErlangExit(new OtpErlangAtom(reason), pid)..

If Pid is not trapping exits, Pid itself exits with exit reason Reason. If Pid is trapping exits, the exit signal is transformed into a message {'EXIT', From, Reason} and delivered to the message queue of Pid. Erlang gives a process the chance to receive an abnormal exit signal from a process it is linked to, without forcing it to terminate: in Erlang speech this is called trapping exit signals or trapping exits. erlang also uses per-actor message queues and has a kill safe design philosophy, so it's not a problem. rdtsc on Mar 28, 2016 [-] It works correctly either way -- externally with exit (Pid,kill) or by the process itself as exit (kill).
