cbench in throughtput mode doesn't work with ryu. We need to limit
queue size to prevent the queue from eating memory up.
The size is arbitrary. It can be the startup parameter. But I think
that we should solve this in the better way. So let's not make it
global for now

Using Queue hurts the performance badly. So let's kill recv_q. It's
not useufl.
Killing send_q is difficult because letting multiple greenlets to send
data to a switch is tricky.

After the datapath connection is close, we call gevent.joinall for
ev_thr and send_thr greenlets to wait for the completion of them.
However, gevent.joinall will block forever since the greenlets sleep.
We can put some junk to the queues to wake them but looks like just
killing the greenlets is simpler.

Later dpset is decoupled with EventQueueCreate.
