ent loop in
this way was not a good approach, so from version 0.13 of this library
all read exceptions will propagate in the first instance out of this
procedure so that they may be caught locally, say by putting a catch
expression around the call to this procedure, and only out of
event-loop-run! if not caught in that way.  Exceptions raised by
&rsquo;proc&rsquo;, if not caught locally, will also propagate out of
event-loop-run!.

<p>This procedure is first available in version 0.11 of this library.
