> Currently, we store all the pages to be written in a list of pending pages (they will be flushed on disk when the transaction will be done).
> It would be very efficient to have a way to update a page which is in this pending list instead of writing it again if we modify it at some point in the same transaction. In other words, when we detect that we are going to modify a page which is already stored in the pending page, then we should not create a new page from it, but instead apply the changes on the page itself.
> That would save a huge amount of disk access...
