Two little issues. Multipathd was shutting down whenever I tried to start
up gdb monitoring on it, because uxlsnr code didn't like getting a signal.
Also, having a lot of overlapping calls to the uxlsnr code caused really
bad things to happen because of a linked list oversight.

This patch corrects both.
