Issue Description:

All,
I'm experiencing a run time crash when trying to use Date, and NSDate. The bug was discovered while playing with the Kitura, and Vapor frameworks. Here is the original issue posted to the Vapor Projects GitHub for additional details:

vapor/vapor#615

All,
While playing with the Hello tutorial, I added a couple of routs. The first returns the "Hello World" string, and the second returns a current time stamp. When executing the route that calls NSDate(), it works as expected the fist time, then crashes the server. Here is the code:

import Vapor
import Foundation

let drop = Droplet()

drop.get("hello") { request in
return "Hello, world!"
}

drop.get("thedate") { request in
var the_date = NSDate()
return "The Date is: (the_date)"
}

drop.get { req in
let lang = req.headers["Accept-Language"]?.string ?? "en"
return try drop.view.make("welcome", [
"message": Node.string(drop.localization[lang, "welcome", "title"])
])
}

drop.resource("posts", PostController())

drop.run()
I'm developing on Ubuntu 16.04, and Swift 3.0 release.

Thanks!
