Basic example seems to be broken (at least on Mac)

I the main program and here is what I'm getting:

bash-3.2$ ./basic
2018-07-05T00:32:05.780+0500 [DEBUG] plugin: starting plugin: path=./plugin/greeter args=[./plugin/greeter]

Hello!

Is "use of closed network connection" expected here? I tried running bidirectional example and there is no problem.

If I remove defer client.Kill() from the host program, the problem is gone (but the plugin process is not killed then)
