i am really not an kernel expert but i found that some kernel helper
process hangs in line 283 of net/core/net_namespace.c (kernel version
3.2)
281 /* Run all of the network namespace exit methods */
282 list_for_each_entry_reverse(ops, &pernet_list, list)
283 ops_exit_list
This looks very much like bug 1181315
