Race Condition: examples/ServerClient/run.sh

[Haximilian]

Despite ./server/server being started first, it's possible for the ./client/client net.dial to execute before the ./server/server net.Listen. This causes the client connection establishment to fail.

Since this is a testing script, I think it's okay to fudge it and add a sleep in between the two commands. i.e., run the server, sleep for a couple of seconds, and then run the client.
