Specify POST requests that don't change the database (or don't need pinning)

[aptiko]

Using the @db_write decorator, I can specify views that change the database although they're GET. What about the opposite? There are POST requests that don't change the database; login is a typical example. There are also POST requests that do change the database, but the change is not so important to be viewed immediately; a possible example is clicking on a "like" button.

This would be great.

This might be solvable in userland with #16, but is also be worth adding a simple/happy-path marker for it in the box.
