[Bug 1144873] Re: "lxc-execute: Failed to find an lxc-init" Error during lxc smoke tests

[Serge Hallyn]

The problem is that src/lxc/start.c:lxc_poll, which checks signalfd for
sigchld from container init, can start after the container init has
exited.  It then hangs trying to talk over the monitor.  The container
init mainwhile waits to be reaped (by the fn which called lxc_poll,
which does waitpid after lxc_poll completes).

We can pretty easily make the race shorter, but I'd like to get rid
of the race altogether and am not sure yet of the cleanest way to do
that.
