<h2>The last error trace</h2>
<p>If the error is uncaught, then callr adds a trace to the error object of
the main process as well. The trace will have two parts in this case.
callr also sets the <code>.Last.error.trace</code> variable for convenience, this is
easier to type than <code>.Last.error$trace</code>.</p>
