-## UDP pair helper
-
-The `common/udppair` module exports a function `makeUDPPair` and a class

-`FakeUDPWrap` emits `'send'` events when data is to be sent on it, and provides

-`makeUDPPair` returns an object `{ clientSide, serverSide }` where each side
-is an `FakeUDPWrap` connected to the other side.

-There is no difference between client or server side beyond their names.
