+ </header>
+ <p>Communication in Erlang is conceptually performed using
+ asynchronous signaling. All different executing entities
+ such as processes, and ports communicate via asynchronous
+ signals. The most commonly used signal is a message. Other
+ common signals are exit, link, unlink, monitor, demonitor
+ signals.</p>
+ <section>
+ <title>Passing of Signals</title>
+ <p>The amount of time that passes between a signal being sent
+ and the arrival of the signal at the destination is unspecified
+ but positive. If the receiver has terminated, the signal will
+ not arrive, but it is possible that it triggers another signal.
+ For example, a link signal sent to a non-existing process will
+ trigger an exit signal which will be sent back to where the link
+ signal originated from. When communicating over the distribution,
+ signals may be lost if the distribution channel goes down.</p>
+ <p>The only signal ordering guarantee given is the following. If
+ an entity sends multiple signals to the same destination entity,
+ the order will be preserved. That is, if <c>A</c> send
+ a signal <c>S1</c> to <c>B</c>, and later sends
+ the signal <c>S2</c> to <c>B</c>, <c>S1</c> is guaranteed not to
+ arrive after <c>S2</c>.</p>
+ </section>
+ <section>
+ <title>Synchronous Communication</title>
+ <p>Some communication is synchronous. If broken down into pieces,
+ a synchronous communication operation, consists of two asynchronous
+ signals. One request signal and one reply signal. An example of
+ such a synchronous communication is a call to <c>process_info/2</c>
+ when the first argument is not <c>self()</c>. The caller will send
+ an asynchronous signal requesting information, and will then
+ wait for the reply signal containing the requested information. When
+ the request signal reaches its destination the destination process
+ replies with the requested information.</p>
+ </section>
+ <section>
+ <title>Implementation</title>
+ <p>The implementation of different asynchronous signals in the
+ VM may vary over time, but the behavior will always respect this
+ concept of asynchronous signals being passed between entities
+ as described above.</p>
+ <p>By inspecting the implementation you might notice that some
+ specific signal actually gives a stricter guarantee than described
+ above. It is of vital importance that such knowledge about the
+ implementation is <em>not</em> used by Erlang code, since the
+ implementation might change at any time without prior notice.</p>
+ <p>Some example of major implementation changes:</p>
+ <list type="bulleted">
+ <item>As of ERTS version 5.5.2 exit signals to processes are truly
+ asynchronously delivered.</item>
+ <item>As of ERTS version 5.10 all signals from processes to ports
+ are truly asynchronously delivered.</item>
+ </list>

+ <p>Control behavior of signals to ports.</p>
+ <p>As of OTP-R16 signals to ports are truly asynchronously
+ delivered. Note that signals always have been documented as
+ asynchronous. The underlying implementation has, however,
+ previously delivered these signals synchronously. Correctly
+ written Erlang programs should be able to handle this without
+ any issues. Bugs in existing Erlang programs that make false
+ assumptions about signals to ports may, however, be tricky to
+ find. This switch has been introduced in order to at least
+ make it easier to compare behaviors during a transition period.
+ Note that <em>this flag is deprecated</em> as of its
+ introduction, and is scheduled for removal in OTP-R17.

- * Most fields in the Port structure are protected by the lock
- * referred to by the lock field. I'v called it the port lock.
- * This lock is shared between all ports running the same driver
- * when driver specific locking is used.
- *
- * The 'sched' field is protected by the port tasks lock
- * (see erl_port_tasks.c)
- *
- * The 'status' field is protected by a combination of the port lock,
- * the port tasks lock, and the state_lck. It may be read if
- * the state_lck, or the port lock is held. It may only be
- * modified if both the port lock and the state_lck is held
- * (with one exception; see below). When changeing status from alive
- * to dead or vice versa, also the port task lock has to be held.
- * This in order to guarantee that tasks are scheduled only for
- * ports that are alive.
- *
- * The status field may be modified with only the state_lck
- * held when status is changed from dead to alive. This since no
- * threads can have any references to the port other than via the
- * port table.
