<p>This executor allows you to multiplex any number of tasks onto a single

thread. It's appropriate to poll strictly I/O-bound futures that do very
|

little work in between I/O actions.</p>
|

<p>To get a handle to the pool that implements

<a href="../futures_task/spawn/trait.Spawn.html"><code>Spawn</code></a>, use the
|

<a href="../futures_executor/struct.LocalPool.html#method.spawner"><code>spawner()</code></a> method. Because the executor is
|

single-threaded, it supports a special form of task spawning for non-<code>Send</code>
