Asynchronously / lazily accessed err.stack is wrong

[CrabDude]

Since stack trace generation is tied to Error.prepareStackTrace, lazily (asynchronously) accessing err.stack causes it be wrong and include both an additional (shouldn't be there) and out of order stack:

require('longjohn')

setTimeout(function() {
  setTimeout(function() {
    var err =new Error('asdf')
    setTimeout(function() {
      console.log(err.stack)
    })
  })
})

Error: asdf

Note /private/tmp/index.js:6:5 and the line after it, should not be included.
