_Upcoming changes may solve this in relevant cases, by inlining syscall operations._
**`loop.mailbox()`** is an unidirectional communication channel, simplification of Go
channels.
It allows to put a `value` in the channel using `put(value)` on the mailbox instance.
To retrieve the value, use `await` on the same `mailbox` instance.
**`loop.spawn(task)`**: Start the task asynchronously. Return an object that allows
the caller to await its result, or shut the task down.

It is also possible to register a synchronous finalizer callback via
`task.set_finalizer`. This is used internally to implement workflow management.
**`loop.chan()`** is a unidirectional communication channel that actually implements two
syscalls:
* **`chan.put()`** sends a value to the channel, and waits until it is picked up
by a taker task.
* **`chan.take()`** waits until a value is sent to the channel and then returns it.
It is possible to put in a value without waiting for a taker, by calling
`chan.publish()`. It is not possible to take a value without waiting.
