[Click] About queues scheduling

[Cliff Frey]

Well, if you wanted another way of doing it, you could change KernelTun to
have a task, and have selected() schedule the task, and have the task go to
sleep+register the select when it receives an EAGAIN.  But maybe the BURST
option is good enough for you, I'm not sure.
