Wait until <em class="parameter"><code>work</code></em> has finished execution. On return, it's
guaranteed that all queueing instances of <em class="parameter"><code>work</code></em> which happened
before this function is called are finished. In other words, if
<em class="parameter"><code>work</code></em> hasn't been requeued since this function was called, <em class="parameter"><code>work</code></em> is
guaranteed to be idle on return.
