[libvirt] [PATCH] Daemonize fuse thread in libvirt_lxc

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

In some startup failure modes, the fuse thread may get itself
wedged. This will cause the entire libvirt_lxc process to
hang trying to the join the thread. There is no compelling
reason to wait for the thread to exit if the whole process
is exiting, so kust daemonize the fus thread instead.
