I was doing some tests using Socket.io and even though everything ran
okay except that I had to manually exit Expresso using ctrl + c.
I tried using `process.exit` inside the `else` block but that would
cause Expresso to output `Failure: Only 1 of 3 suites have been
started`. Using a timeout seems to fix it despite the fact that I'm
using 0 as time. Not really sure how this works, but it does :)
