__sync_wake: 62 sync wake failure : Broken pipe with --share-net option

[ik-nitk]

I am trying to start a lxc container deb1 and use --share-net to start another container deb2 to share the network namespace. But both in fedora and ubunut i and getting error below:

issue |

[root@blr-vxr-056 ~]# lxc-start --share-net deb1 -n deb2
lxc-start: cgfs.c: handle_cgroup_settings: 2077 Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start: cgfs.c: handle_cgroup_settings: 2077 Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start: sync.c: __sync_wake: 62 sync wake failure : Broken pipe
lxc-start: start.c: __lxc_start: 1080 failed to spawn 'deb2'

Steps to recreate	command
start a container	lxc-start -n deb1
get pid of init process of that container.	or create link in /var/run/netns/deb1 -> /proc/56298/ns/net
start another container	lxc-start --share-net deb1 -n deb2

The namespace sharing logic has been reworked substantially and should work correctly now.
