+It's good to keep a model of our computer in mind when writing code.
+Many errors might seem obvious once we do this.
 
+CPU: Executes instructions on cores and threads.  Each thread has its
+     own cache with a shared cache between them.
+     
+Memory: Connected to the CPU, usually _very_ slow to access in CPU
+        scale time.  This is why values get (and stay) cached.
+        
+Synchronising Cache and Memory is the CPUs job.  We don't have to
+worry.  BUT: concurrent prograbs CAN break this mechanism.
