==Contents==
A few of the database updates required by various functions here can be
deferred until after the result page is displayed to the user. For
example, updating the view counts, updating the linked-to tables after
a save, etc. PHP does not yet have any way to tell the server to
actually return and disconnect while still running these updates (as a
Java servelet could), but it might have such a feature in the future.
We handle these by creating a deferred-update object (in a real O-O
language these would be classes that implement an interface) and
putting those objects on a global list, then executing the whole list
after the page is displayed. We don't do anything smart like collating
updates to the same table or such because the list is almost always
going to have just one item on it, if that, so it's not worth the
trouble.
