I'm trying to test a class that starts a DRb server. I have a stop
method in the class that does a @drb_thread.kill. But when I try to
start the DRb server up again, it's throwing an exception:
#<Errno::EADDRINUSE: Address already in use - bind(2)>
Any way around that? Do I need to wait a couple seconds between each
run for the port to clear up?
