Thanks!

What's the use case?

[urish]

N/m, just saw the other issue that you opened with the explanation. Can you please add a test case as well?

[jamiemchale]

I have a bunch of Mocha tests that run in sequence. I was closing the server on the after() in each spec, and loading it in the before() in others. Sometimes the close() on the server didn't complete by the time the before() of the next script ran, so a port in use error was raised.

Sure, I can have a go. This is one of my first open-source contributions!

[urish]

That's wonderful, keep them coming :)

If you need any assistance, feel free to ask

The close test was failing on Node v0.10 - it seems that the server wasn't loading in time for the close callback. I'm not sure if there is a tidier or better way of testing this?

Thanks! Did you try to use setImmediate instead of setTimeout?

Released as 0.5.1
