Sharing data
In the example given in this chapter, we saw how to share information between threads in addition to synchronizing threads--this in the form of the requests we passed from the main thread into the dispatcher from which each request gets passed on to a different thread.

After this, we have to ensure that only one thread can modify the data, and that the data does not get modified while it's being read. Generally, we would use mutexes or similar to ensure this.
