>
> The buffer cache's pin, unpin, and write operations are not exposed to the
> context of the overall on going operation. To some extent, the pin operation
> have some context (e.g., not incrementing a stat). Changing the buffer cache
> interface every time we want to incorporate contextual information is not
> sustainable. Instead, a user of the buffer cache should provide a context
> object that can hold all the necessary information of a given buffer cache
> operation (e.g., incrementing stats or processing the header when reading a
> page in a pin operation).
