 For every location in memory, we keep track of a stack of borrows (`Uniq(_)` or `Raw`), and potentially "top off" this stack by freezing the location.
 A frozen location is never written to, and no `Uniq` is pushed.
 
-Whenever a mutable reference is created, a matching `Uniq` is pushed onto the stack for every location "covered by" the reference -- i.e., the locations that would be accessed when the reference is used (starting at where it points to, and going on for `mem::size_of::<T>` many bytes).

 There is more to a pointer, or a reference (I am using these terms mostly interchangeably), than the address in memory that it points to.
 
 For the purpose of this model, we assume that a value of reference type consists of two parts: An address in memory, and a tag used to store the time when the reference was created.
