zombie process after (attach and run_command)

[fanyeren]

i've tried
pid = c.attach do
LXC.run_command('/sbin/ifconfig')
end
Process.wait(pid)

and this problem is fixed

You can also call

c.attach(wait: true) do
  ...
end
# No Process.wait needed

I'm considering switching the wait flag to default to true, but that would be only for 2.0.0.
