This can happen if the server has a NICKLEN setting which is less
than the length of the specified nick. With this patch we now grab
that nick and use it moving forward, instead of failing because we
didn't get back the one we specified, in the connection response.

Looks like we import "from time import sleep" but were calling "time.sleep" which is scoped into the wrong namespace.
