Description of problem:
Not exactly sure how to reproduce the problem. I am doing quite a bit of heavy development that uses libvirt. The libvirtd.log file prints out:

A second process is spawned by libvirt as well:
root 22049 24375 0 11:49 ? 00:00:00 libvirtd --daemon
root 22353 22671 0 11:58 pts/4 00:00:00 grep --color=auto libvirt
root 24375 1 2 11:00 ? 00:01:40 libvirtd --daemon

kill -9 of the non-init parented libvirt unsticks the system ie:
[root@beast libvirt]# kill -9 22049

Then things start working again.

Version-Release number of selected component (if applicable):
[root@beast libvirt]# rpm -qa | grep libvirt
libvirt-0.9.6-2.fc16.x86_64
libvirt-python-0.9.6-2.fc16.x86_64
libvirt-client-0.9.6-2.fc16.x86_64

How reproducible:
hard to reproduce

Steps to Reproduce:
1. execute vm starts/stops
2.
3.

Actual results:
libvirt launches a second process and wedges

Expected results:
libvirt should not wedge

Additional info:

killing the second process unwedges libvirt
