From 7d84963667c9c1eff2dd8da44b4fc76fd8890f7c Mon Sep 17 00:00:00 2001
From: Mark Michelson <mmichelson@digium.com>
Date: Fri, 9 Nov 2012 23:23:32 +0000
Subject: Add a test that ensures that taskprocessor listener callbacks are
 properly called.

The new test is a bit raw in that it uses magic numbers, but that
can be improved upon easily.
