go - get notified when http.Server starts listening

When I look at the net/http server interface, I don't see an obvious way to get notified and react when the http.Server comes up and starts listening:

ListenAndServe(":8080", nil)

The function doesn't return until the server actually shuts down. I also looked at the Server type, but there doesn't appear to be anything that lets me tap into that timing. Some function or a channel would have been great but I don't see any.

Is there any way that will let me detect that event, or am I left to just sleeping "enough" to fake it?
