[LRUG] Making Rails time out

[Rob Anderson]

Yes, this would be a good way of implementing the test if I were writing the client. But I'm actually providing the service.

This probably falls into the class of tests which it is the client's responsibility to implement / simulate.  But in our particular case it would be handy to have the server be able to do this.
