For the sake of using `gosher`, the main issue is whether your `netcat` implementation does exit or not when its standard input gets closed. Notably, the original `netcat` implementation by hobbit@avian.org does **not** exit, while other common implementations -(OpenBSD `netcat`, `ncat` from the nmap project, and GNU `netcat`).
