From: Ondrej Lichtner <olichtne(a)redhat.com&gt; When the lnst-slave process forks, the parent process should wait for the result returned by rest of the add_namespace method. Otherwise 2 result messages are created, which could cause the Ctl <-> Slave message lock-step to be desynchronized and cause race condition issues.
