Post process is used to make alterations to the form, after the form  
has already been processed.

Use 1:  Node Preview.

We can't display unfiltered data to the user from the _POST, so we  
have a post_process on the node
form which adds the node_preview form element using the already  
filtered values.

Use 2 : Image module.

There's a similar use case for the image module too, although james  
might know better.
