Bug 149.

Fix for when local listen fails to start properly.
It was observed that slon can wait for the local listen cond to be set where the local listener
thread stops on an error. In this case we want to signal the mutex but flag the local listener
as not having started. The main slon thread should then abort.

This patch had previously been reverted due to an improper merge. This
version should have been merged properly.
