pry-remote just hangs without giving prompt.

[entrity]

I'm running pry-remote 0.1.8. Although it appears as if I can start the listener with pry_remote, the client pry-remote just hangs without giving me a prompt.

After calling binding.pry_remote in my ruby code, the ruby stdout outputs:

[pry-remote] Waiting for client on druby://127.0.0.1:9876

Then I run pry-remote from a shell, and it appears to just hang. Curious what was going on, I ran socat between the pry-remote client and the listener on port 9876 and got this dump (hex on the left, printed chars on the right):

Do you have any insight? Why is the client not giving me a prompt?
