// This test starts two clustered HTTP servers on the same port. It expects the
// first cluster to succeed and the second cluster to fail with EADDRINUSE.
//
// The test may seem complex but most of it is plumbing that routes messages
// from the child processes back to the "super" master. As a tree it looks
// something like this:
//
// <super master>
// / \
// <master 1> <master 2>
// / \
// <worker 1> <worker 2>
//
// The first worker starts a server on a fixed port and fires a ready message
// that is routed to the second worker. When it tries to bind, it expects to
// see an EADDRINUSE error.
//
// See https://github.com/joyent/node/issues/2721 for more details.
