> Currently, BufferCache has an interesting behavior such as:
> 1. CreateFile doesn't create a file but only create a name-id mapping in memory.
> 2. To get the id of a file, the caller must have access to the map associated with the buffer cache.
> 3. openFile. If create file was called before openFile, then it creates the file. If the file already exists, it deletes it and create a new file.
> This should be fixed and given clear behavior that matches the expected API. All usages of the buffer cache must be fixed as well.
