          The system executor represents an execution context where functions are
          permitted to run on arbitrary threads. The <code class="computeroutput">post()</code> and <code class="computeroutput">defer()</code>
          functions schedule the function to run on an unspecified system thread
          pool, and <code class="computeroutput">dispatch()</code> invokes the function immediately.
