I'm going to be doing some work with 9P and high-latency links this
summer and fall. I need to be able to test things over a high-latency
network, but since I may be modifying the kernel, running stuff on
e.g. mordor is not the best option. I have enough systems here to do
the tests, I just need to

any reason loopback(3) wont work? it has options for delay and latency.
