    <title>The Event Loop</title>
    <para>
     The Event loop monitors the state of sets of futures and or channels (targets) in order to perform read (<methodname>parallel\Future::value</methodname>, <methodname>parallel\Channel::recv</methodname>) and write (<methodname>parallel\Channel::send</methodname>) operations as the targets become available and the operations may be performed without blocking the event loop.
