* BOB now cleans up tunnels, although they can take up to 5 minutes to
disapear. This is due to the fact that the streaming lib doesn't
actually remove the connections properly and kill them off when the
manager is destroyed. I'm not certain if this is a bug, or a feature,
but it sure is annoying, and you have to wait for the connections to
time out. What should happen is the streaming lib should cause an IO
error to the pending read or write.
