The first call to addasync is running in sync way (hmmm... I should write a
better explanation, but my English is limited ;-)...)
Then, it prints the first 3.
The call to addsyn is runnning after that, then it prints the 6
Meanwhile, the first addasync queued a new call in process.nextTick.
In the next tick, that call will be run, producing the second 3
Make sense?
